Use a Little Care & the Battery Compartment Issue is a Non-Issue
921101
Read the reviews before purchasing and decided to try it out. Have had none of the battery compartment leakage issues, and didn't do anything like adding grease or silicone sealer. All I did was make sure the battery compartment cover was fastened reasonably tightly(by-hand-tight, no screwdriver) and after each use I let the unit thoroughly dry out then open the battery compartment to make sure it's dry as well (it has been each time so far). As for the unit's in-pool performance, it's dramatic. I was skeptical about how much power this little leaf-sucker would have based on how slowly the blades appear to turn, but man does it do the job! The filter bags it comes with are large enough to hold a lot of debris before needing emptied, and catch everything but the finest of particles like actual dirt or very fine-grain sand. For that I might recommend getting the micro-tech filter bags as an add-on. I haven't ordered / tried them out yet. But all-in-all, no hoses to hook up, easy to use, easy to clean, runs a good long time, and with reasonable care I've had none of the battery compartment issues, so I'd 100% recommend this leaf vac / pool cleaner.

As a side note, I used to use the Aqua Tech Water Broom, also by Pool Blaster, and liked it very much as well. However, it had no where near the capacity of this leaf vac, so I was constantly stopping and emptying its little filter bag. This is a huge improvement over that for use in a large pool.

Ok, but the battery compartment could be easier to open. My 91 year old mother-in-law will hardly be able to change the battery. From experience these batteries being in an outdoor environment will likely need to be replaced after at the most one year. The construction leaves it also a little flimsy in the joint. That being said, it glows nicely marking her driveway, and making it much easier to back out of.

Picture the perfect day: Beautiful restraunt, amazing food, conversation that keeps flowing and never falls dead, being attracted and yet there is real substance and affection.  Then a hike a beautiful day, perfect weather with hugs, empty trails and laughter and dialogue.
Then arrive back at the car and find the battery very dead.  (new car, left the lights on)  After a moment I reached into the glove compartment, came and got this funny bag of wires that I had charged, fumbled with the putting it together then grabbed by phone so I could see what terminal was positive and negative and came back to the car and turned the key -- Booom the car started immediately, I waited till the idle sound of the engine went to normal, disconnected everything and got back in the car in under 5 minutes.
The lady friend saw me handle a stressful situation with being prepared, honest about not being sure what what happening and a speedy resolution.
I would like to point out that in one use this device paid for itself both because now I have a third date, and because it would have been double what I paid for road side assistance and a 2 hour wait.
The mind blowing part?  The jump did not even use a single bar of battery from the power bank.
Basically, buy one, and be awesome

I had an unusual problem, one I've never had in many years of experience with gadgets and mechanical things. I could not open the battery compartments on either one I bought and had to return them.

Revised review:
The HisGadget folks sent me a new one and it works perfectly. That speaks very well for them. Thanks.

Car batteries have been sealed and maintenance free for decades so checking fluid levels is a skill most people don't have. This battery has to be set up properly and properly maintained to get its full life.

First thing: this battery is shipped dry so you will need to fill it with battery acid (sulfuric acid). Home Depot sells these Basement Watchdog batteries so I picked up a box of acid at my local home depot.

This acid can burn you and damage clothes and just about anything it gets spilled on so use great care. Safety glasses are a must and so are gloves. Have clean water and paper towels at hand to wash off any acid that gets on you and to wipe up any spills.

I'm a chemist so filling the battery with acid correctly was simple for me but I can see many opportunities to get this battery off to a bad start. First off there is not enough acid in the acid pack to fill each of the cells to the top. There are six cells and the acid must be divided equally to each cell.  The acid Z pack contains 6 quarts of acid. I used a glass beaker to measure out the acid and I added 32 ounces of acid to each cell. There was still considerable space left in each cell so I added two ounces of distilled water to each cell. A month latter I added another ounce of water to each cell.  You must add distilled water. If used regularly the minerals in tap water will slowly neutralize the acid in the battery and over time will destroy the battery. In an emergency it would be OK to use tap water but I'd only do that once.

I left the bottle of distilled water and a small beaker sitting next to the battery. I'll check the acid level every month until I get a feel as to how often I will need to add additional water. I'm guessing I'll need to add water about every four months as long as the battery sump pump is not used. If the power goes out and the pump runs on battery power I'll be sure to check the fluid level since the heat of discharge and recharge will cause some water loss.

The unit has a probe that alerts you if the fluid level drops too low. I would not recommend waiting for the warning light to come on. It's like the oil light on your car. By the time it comes on you are way too low.
Also the cells are not connected and the monitor only checks one cell. All the cells should behave similarly so if the monitored cell has water in it the other should also but there is no guarantee on that. At $150 each I want to get as much life out of the battery as I can so I'll be checking the fluid levels and adding distilled water as needed.

The battery life is phenomenal! I haven't had to charge this in over 9 months. Sometimes the keys do fall off and the soft, foam sides are peeling away from the keyboard. The spacebar stopped working after 8 months. For the price, this is a decent product. Just be very gentle with it. :)

Good choice. You'll need to buy new batteries when it arrives. Both my buddies had to do the same thing. Honestly, for the price, choose another product.

The place which contains the battery is not good enough. The cover of the battery is not hard enough, and I just open several times and it looks like that it may be broken soon.

I've had the CT14 for 4+ years, and have used it just about every weekday, averaging 2-3 hours on the phone per day.  The on-board battery is finally starting to lose charge; if I forget to put it back on the charging unit at the end of the day, it may only last me half a day the next day.  Overall, I've been very pleased with this phone.  I've dropped from desk to the floor on more than one occasion (landed on carpet) with no noticeable effects.  I have a very noisy laser printer, and callers on the other end cannot hear it.

Just recently, I have noticed a bit of static sound when I hear the dial tone, but it goes away when I am actually on a call.  I think the unit may have been damaged recently by a power surge, which could be affecting my incoming calls on my digital phone service (phone through internet service provider).  Since the battery is not as good as it used to be, I'm opting to replace my CT14 to rule it out as the culprit.  If after replacing the modem I still have issues, I will know it is my ISP/modem and not my beloved CT14.  I will update this post once I know for sure.

Just installed, and is presumably working. My problem is with the battery compartment marking. Because the battery polarity is marked with features molded into the plastic (that are the same color as the rest of the housing), they are exquisitely difficult to see, especially when looking up at a ceiling-mounted unit. The main time I expect to interact with this device is when replacing the batteries, and every time I do, I will be reminded that it was designed by fools.

This is a fairly difficult repair to undertake but worth the money, if your mechanical repair skills are up to the challenge. So far, the battery has performed exceptionally. Stil indicates 95% health after 2 months of use.

Opening that battery compartment invites one thing - disaster. As soon as you do that, your warranty with the SP is out the window. Also if you don't know what you're doing, you can damage your machine very quickly. The SP gives you 20 hours of play on one charge if you don't use the backlight, and 10 if you do. A battery that advertises being good for only 10 hours is bound to get less then that. Also, why would you need another battery? You can always get a car adapter if you're going on a long road trip, and you always have a home one for home charging. All in all, this is the worst accessory I ever saw Intec come out with! AVOID at all costs!

I initially had a problem with very poor battery life (lasted one day off the charger), but after a conversation with customer support yesterday, I believe (I hope) that problem may be a thing of the past.

1.)  Holding the ON/OFF button, remove the battery, then reinsert it before letting go of the ON/OFF button.  It will now show you to be in Safe Mode.  (If you decide not to finish this procedure, remove the battery and reinsert to get out of safe mode.)

2.)  Log into your Logitech account, click on Downloads, then click on Firmware.  You will now plug the USB cable in, and follow the instructions.  (No different than when you update your remote codes.)

I'm on the second day with the remote still showing fully charged, where before it was dead after 24 hours.  (Some people may not care about this, but I would rather replace batteries once every month or two than be forced to cradle it every night...)

Hopefully this solved the battery life problem for you as (I think) it did for me.  This is still such a new remote, they are continually working on the firmware to improve it and fix problems.  (For a later improvement, how about giving it a delayed "System OFF" that could be used as a sleep timer?)

That being said, I do love the remote.  It doesn't function any better than my 880's (I have two of those), but the button layout is so much better (easy to operate without looking at it to find the correct buttons).  The touch screen really isn't any more functional than the other Harmony remotes that don't have it, but I suppose they put it in for the techno-geeks who want a touch screen on their remote.  I would have been happy with large, easy to hit buttons around a regular screen, with the RF capability.  We all know the next version will have the RF added to it (880/890), and from what I have heard, they already have provisions on the circuit board for it.  They just want us to buy this one, and then the RF version.  I personally don't appreciate that kind of marketing, I would have rather had a choice of a RF or non-RF remote.

Update 7-6-17: I bought this in December of last year and have used it a hand full of times and the battery pack has stopped charging. Luckily it comes with an alkaline backup so it's not going straight in the garbage...yet. Supposed to have 2 year warranty on the battery so we'll see how that goes if I can find out how to mess with that through Amazon.

Previously:
I will update this review if I have problems with the light, but so far, it has exceeded my expectations.

Spot light output is adequate and equal to or better than the competition. I thought the ground-light was more of a sales gimmick but it is actually very handy. It really spreads out and illuminates your walking path. The unit appears well-built with an o-ring on the battery door and good action on the switches. I haven't pulled it clear apart but it appears there are nuts inside for the clip mount. My screws seemed loose, so I tried to tighten them but they just spin without getting tighter. Hopefully this is not a point of problems in the future.

If I could knock half a star for the charger, I would. Taking the light in and out of the charger is a bit of a challenge at first. You sort of have to twist it into the "fingers". I'd prefer to have a little more simple removal and loading, but I'd also rather have something that holds it too well than not well enough, so the star stays.

Update: A little more than a year later the internal battery will no longer hold a charge...

Working fine but certain well-used keys after just a month are getting a white halo around their letters!

Purchased for my XPS 13 L322X that couldn't get more than 1hr anymore on its original battery, and that was in battery saver-mode besides.

Took about 30min to install, but this isn't my first time taking apart laptops.  It worked for a few minutes, then the laptop started saying there was no battery.  I took the laptop apart, and realized I didn't plug the battery in all the way.  Certainly no fault of the product.

I charged the laptop last night, and have been using the laptop for about 2.5 hours, and still have about 2.5 hours left on the battery, which was about what I remember when it was new.  For the price, I wish I had bought this battery a year ago.

Will update in ~6 months to say how it's working then.

Update ~6mo later:  getting anywhere from 3.5-4.5 hours still. I have noticed a couple keys on my keyboard aren't working reliably, so I'm going to clean it out, then am probably going to re-install the keyboard and see if that helps. May just be a hazard of doing such an install yourself.

Update ~12mo later: the battery is still lasting 3.5-4.5h depending on use, however the keyboard is still having issues and the touchpad has since starting sticking up strangely.  I just opened the laptop up to try and get the keyboard working fully again, and realized the battery is swollen in multiple places- thus causing the touchpad to stick out.  I'm wondering if this is the cause of the keyboard issues as well.

After a quick google, I found: "Dont charge or use it at all, because lithium-ion (Li-ion) batteries that are bulging have already bypassed built-in safeguards and are swollen with gases. Continued charging or use could lead to a runaway reaction that results in a fire or an explosion."

So, I'll now be removing this battery and disposing of it out of fear of it starting a fire.  1 star, as this should have lasted more than 12 months.

Currently using it and not bad at all! Sadly the light stays on if it's still connected and battery power is still on.
