I needed to order to replace one that broke after about seven years. This was easy to figure out how to go on and works great. Very easy!

For some who is DIY-challenged, this was easy to install.

I was surprised to see this shipped with cables and adapters.  It made connecting to the car much easier.

It works.  Not much to say about that.

The only negative about it is that it has a morse-code interface... one button and one light serving multiple functions.  It's not really complex, and easy to follow with instructions, but when you don't have the instructions handy, it's not fun to wonder whether to push and hold or is it one flash, two alternating flashes, a steady light, red, or blue...

I've been looking for a new controller for my decades old wall unit. OMG, that thing is old. I was hoping I could get a digital thermostat and Bam. I did! I have to say, the instructions are a bit lacking for older thermostats. I have a two-wire thermostat, and it was painful trying to figure out how to connect this. but after a few web searches and an explanation of what the initials mean, I got it working and it works fabulous. Woke up this morning to the heat having been on for 15 minutes, which is nice when its cold. It was super easy to program and hang on the wall. It only took a few minutes to finish and hang up after getting the wires plugged into the right posts.

Although it would have been helpful to have a second pair of hands, I had to assemble this item by myself and was able to do so just fine.  I found the directions very easy to follow.  There were a couple of places where I had to wrestle with the parts to get the bolt holes to line up, but I was able to make it work.  If you can change a tire on a car without someone showing you how, then you can probably put this together.  On the other hand, if mechanical aptitude is not one of your strengths, it might be good to get help.

I agree with other posters here that setting this up could have been much simpler. Yet, once I figured it out it worked like a charm. I use this for my desktop computer to play on my living room stereo across the house and it works seemlessly. I use the remote app that you can get for the iPhone 2.0 and it make it even more fun as I can change songs straight my iPhone without having to go to my computer.

So far this works pretty good. It did take me a little bit to figure out how to sync it with my phone and took a few times trying to figure out the directions but I finally got it and it's working now. I haven't figured out how to charge it yet so that is a problem. I was given this product at a reduced price in exchange for an honest review.

I was very hesitant that I would not know how to wire the contacts to the Honeywell RPWL3045A1003/A Wireless Premium Portable Converter/Extender/Push Button.
The directions were no crystal clear but good enough for someone with technical experience to figure out.
I had a hard time trying to squeeze the wires out of the contact to make it flush with the housing. In the end I ended making a small 1/4 inch cut on the side of the plastic housing to fit the wires.

This is so simple to use and works as it is supposed to work.

Well worth the price and easy to understand its operation.

I purchased this product on a whim and so far, it couldn't have been easier.

When we bought our house, our garage does not have built in lighting beyond the garage door opener -- thus at night if we needed something, it's always either a flashlight or open/close the garage.

We tried a Mr. Beams motion sensing light -- this worked well; however, batteries came and went.  We do have hanging halogen lights out there for extended work, but they require being manually plugged in each time as there isn't an on/off switch.

Enter this wireless R/C electrical plug:  Simply plug the plug control unit --> plug in the halogen lamp --> voila!  An on/off switch to turn on both sets of lights.

It's simple and it works -- my favorite type of solution (... beyond free).

(The only reason for 4 stars instead of 5 is that the battery cover on the second remote was nigh impossible to get off.  The casing on the remote ending up separating during the process.. but it was easy enough to snap back together and it still works).

After watching YouTube video I was able to see how to easily set up and take down. Wish it came with directions, but works great

Works well! It's true that there weren't any instructions that came with the key ring but there were many helpful reviews on Amazon that helped me figure it out easily. It can be a little frustrating at first but eventually it gets easier. To get it unlocked, twist the keyring into a figure eight. To lock it up again, place the ends of the key ring together first and THEN twist into a figure eight.

The key ring came by itself in a regular mail envelope. It was thinner and smaller than I imagined but all of my 4 keys, 1 SOG key knife, 1 electronic door fob, 1 eyeglass screwdriver, and 1 flashlight fit onto it with plenty of space left. The keyring is thin enough to fit through all of the different holes but thick enough to reassure you that it'll last. My key ring came in red but the seller said that you can contact them right after placing your order to choose a color. (If you want to contact them, you go to your Order History, look for this item, and then click the Contact Seller button)

The main reason I chose this key ring instead of the cheaper, more painful split rings is because I like having the option to easily and painlessly take out keys even though I don't take them out very often. I've owned this for about a week so far (as of September 17, 2015) and I will update my review if I experience anything else.

Item came with no instructions, but it was easy to figure out.  Could not get  the stand connected to the phone to pop up, it seemed to be stuck to one side, hence my knocking it down a couple of stars.  Thankfully, the belt clip from the outer shell can be used as a back up.  Decent price for what you get.  Will update after a couple of months of use.

I used this to replace a failing switch on my Warn winch. Had to to some jimmy-rigging to make it work since the screws on one didn't fit the other. I wanted to use the Warn mount but new switch. A couple tweaks made it work. If I remember correctly, the wires are a different color too, but that was easy to figure out. Has been working great since install.

It was suggested that I needed one of these for an upcoming trip. After doing a bit of research, this seemed to be the best of this sort of thing.  After seeing it first hand, I am very impressed with both the design and the construction of the Add-a-Lock.

It took a few minutes to figure out (without the use of included instructions), but once I got the hang of it, it is very easy to work. Most children 5+ could be taught how to operate it.

I did not use directions on purpose as I had concerns about how easy it would be to get out of the locked room in case of fire or other emergency. Yes, it will slow you up, but literally only by a few seconds. Simply pull the red thing up & out and the door is free.

I tested it on various doors in our home - and it worked on all of them It appears to work on any door with a latch hole (w/ striking plate?) on the door frame that also opens into the room. Once engaged, no one from outside will be coming in, with or without a key unless they come literally *through* the door itself.

I like another comment about keeping the directions with you for going through TSA - I can see this is something they may question. Until you see it in action, it is hard to understand the purpose of a piece of plastic chained to a hunk of metal.
