Very Handy Gadget~~Saved Me Some $$!
351587
I recently bought a 2013 SUV, so even though it's still "new", I know it's just a matter of time before that lovely little engine will make an appearance~~even if it's just to remind me it wants clean oil or a clean air filter. So, I decided to look into OBD units to save myself some costly trips to the shop simply to have diagnostics run. I decided to go with this Oxgord Bluetooth OBD II~and it is very handy! It is a simple matter of locating you diagnostics panel, plugging this unit in and following the prompts! It takes no time at all and is pretty straightforward to use. I have used it twice and have been able to save myself some cash by having it tell me I had a worn out vacumn seal on my gas tank door. I did receive this at a promotional price, but I highly recommend this item for anyone(especially women who dislike going to the mechanic) who wants to try to "self diagnose" before going to a shop!

This handy little gadget helped me to "jury" rig my DVD/VHS combo, cable box, Roku Stick, and HDMI TV to work & play nice together! I would try to explain but it would get me all confused & discombobulated again, let's just say it took me a lot of trial & error & brain power to figure it out with NON-Tech brain.

Worked great on troubleshooting two 2006 Volvo XC90 that had "gear shift selector service required" and "anti skid service required" messages on the dash. Also handy for clearing routine maintenance reminders. This unit shipped Amazon Prime from the United States, not China. The money saved by DIY more than paid for the tool the first time I used it. The included software installed and worked on a laptop with Windows 7 Pro 64 bit edition and Internet Explorer 11. Instructions are a little dicey, but shouldn't be an issue for anyone mildly tech savvy.

Note: It is web browser based and I needed to put[...]t in the "trusted sites" list in the security tab of Internet Explorer, otherwise it would not display the log in page.

What a clever little gadget this is!  I am all but totally computer illiterate, but I am savvy enough to know that I needed more little port things so that I could plug more stuff into my computer...and I knew that I wanted something with a long enough cord so that I would be able to hide the wires down below eye level.  I looked at doobilators that cost LOTS of money, and I suppose that if I had any idea why spending a lot of money on something that I could also spend just a little bit of money on was important, maybe I would have bought one of the expensive things...But I don't, so I didn't. And you know what? My computer doesn't seem to mind that I bought a bargain doobilator. It works perfectly, and any time my computer works perfectly, I am more than happy.

This little gadget is so cool! I am no longer blind of exactly how much electricity my electronics and appliances are consuming.

Armed with my Kill-a-Watt, I now know that my old fridge is costing me over $200 a year to operate, and with a simple online calculator I can figure that a new one will pay for itself in a few years.

The Kill-a-Watt is also useful for determining which items in your house are consuming "ghost voltages" -- electricity wasted even while your electronics are switched off. With this knowledge you can decide if you should switch these items off with a power strip.

So why not 5 stars? The P4400 model (the one you are looking at now) does not calculate the cost of electricity by itself. You have to make those calculations separately. Although this is not difficult, I wish the manual told you how, so you don't have to figure it out yourself. Also, my unit fluctuates between 0-1 watt when nothing is plugged in to it -- slightly annoying, but far from catastrophic.

Keep in mind, the Kill-a-Watt won't save you any electricity by itself. It is the decisions you make armed with the knowledge the Kill-a-Watt provides that can save energy.

My conclusion: the Kill-a-Watt is the perfect tool for anyone interested in saving money and/or the environment. I like.

Handy little gadget for turning on my outdoor patio string lights with the touch of a button!

This thing works great.  Very handy.  Remember to be careful when changing the battery.  The cover can come off if dropped or you move you're fingers around while using it.  If you press down too quickly, or rather too late when sliding the battery cover back on, you may bend or break the tabs which hold the battery cover on.  I almost did, but then agin I wasn't really paying attention to what I was doing.  Just be careful and go slowly and you will be OK.  I actually put a small piece of gaffer's tape over the battery cover, just in case. Other than that, this is a very handy device and works quite well.

First let me just say that I moved into a house with a garage door opener- no remote to be found. I tried syncing the garage door opener buttons in my car, no luck. I tried purchasing two different "universal" garage door opener remotes, nothing. I called manufacturer after manufacturer, trying to find answers, all to no avail. I did a TON of research online and finally came across this remote. This little device worked like a charm. It took literally seconds to set the dip switches and VOILA! It. Actually. Worked. THANK YOU!

This little device is excellent! I was so tired of misplacing my cell phone when I didn't have pockets. Now my phone is always with me and handy when i need it! I can't count the number of people who see it and ask me where I got it! I have ordered several more for friends. A great little gadget for a low price!

I'm not going to expect much from a $20 OBDII scan tool.  It does it's job and pulls codes from my car with no issues.  It's been really handy to have around, not just for me but for several friends and family who have borrowed it.  With the price of gas nowadays a couple of trips to town to read codes would almost pay for this.  Well worth a $20 investment to keep around the garage to save yourself a little time and money if you ever need a code read from your car.

I paid $40 here on Amazon, in some of the reviews it sounds like this item used to go for $30. I suspect high reviews and popularity have allowed Amazon to raise the price some (33%? sheesh) or maybe they were just running a great sale a while back. Nevertheless, it is a simple to use tool and works very well. Glad I bought it, but I'd be even gladder if they felt like crediting me back the extra $10 :)

By combining the code this tool returned and some internet digging I was able to learn that my car hates platinum spark plugs and that standard copper plugs would smooth out my car's hesitation problems. Check Engine Light is now gone, thanks Autel!

What a handy little thing! I am so happy that  I bought this. I didn't think I would use it a lot, but I use it all the time.
