Affordable and works great! Definitely recommended for those unexpected situations.

I bought this pump a while back when I noticed the tires on my new bike were a bit deflated. It's nice and compact, attaches easily to my bike, and it doesn't feel super cheap. It will take quite a lot of pumps and effort to get your tires to the correct psi, but that is to be expected for something so small. Using this pump is like warming up before an intense ride, haha (especially if you're a beginner like me).

We purchased Battery Brain because my daughter's vehicle has an un-identified drain on the battery.  Estimates to find the problem are in the hundreds of dollars.  Because she lives on college campus hours away from home, we can't come to her rescue when her vehicle is dead.  So, after having the device installed by our mechanic, she is able to use the remote control (included with the kit) and re-connect her battery and start her car when needed.  I definitely recommend an auto mechanic hooking it up...it is more difficult than what the installation guide says, especially if you are not an electrician or mechanic.  Overall, a great purchase for our peace of mind.  I've recommended it multiple times since our purchase!  Thanks.

I was glad to get two of these items for a good price.  This is something that would come in handy in an emergency.  I am a police officer and could have used it on a couple of occasions when a child was locked in a hot car and we could not get the door unlocked.  Obviously, it is not something I can put to the ultimate test until the time comes to use it.  I did activate it on a non-vital surface to be sure the spring mechanism works.  I am seriously considering getting it for my grown children at Christmas.

I purchased this little "stunner" as alternate protection where I can't have concealed handgun etc.
At first I put just an average battery in the unit and got NOTHING except a flashlight.
After communication with the seller I purchased a duracell battery and plug it in.
My husband did not expect it to work by simply exchanging one new battery for another,
luckily he didn't have it touching him when he selected "stun" it was funny watching him
almost drop the stun gun when the electricity zapped across the terminals!
Comfortable enough to carry without worries!
Recommended to any woman who has to walk to her car after dark!

We get occasional blips where the power will go out for just a second or two. I plugged our cable modem, router, and NAS into this and it's completely eliminated any concerns.  We had one such brown-out just the day after I set it up which was very satisfying to weather unscathed for once.

I've been using this for months now, it's a set it and forget it device.

I picked this model because it was the cheapest unit with a display and USB option that also takes off the shelf batteries.  I haven't used the USB yet, but the display is nice to know the load.  You don't need the fancy and expensive real sine wave stuff unless you're using analog devices (CRT monitors, sound equipment etc).

The internal wireless modem part on my Gateway computer broke down and I couldn't get a wireless signal anymore so I was looking for something cheap and efficient for me to use while I price around a repair.  What attracted me to this particular wireless adapter were:

1)  Reviews - mostly good, and I trust my fellow reviewers!
2)  Price - definitely worth around the $12.99 I paid for it.  I consider it smart to price shop considering the price it would be at a big box store.  Only trade off was the waiting at the most, a week, for it to come.  What can I say?  I love getting a good deal!
3)  Antenna - this was a feature that I really don't know whether or not it makes a difference, but it was a good bonus, I think.

Overall, very satisfied with it's usefulness.  I eventually got a lighter laptop for portability sake, but now I have a backup just in case!

Easy to use and fits the bill. I wanted an affordable (cheap) remote control for our sunroom. My wife loves plants and our sunroom has a little jungle of them, a small fountain with a light, and several little lamps. The room gets a little plant crowded over winter as some outdoor plants come inside for the winter. Its was a pain to reach behind the palms and plants to plug in the fountain and switch on the lamps. Enter Etekcity. It took 5 min to setup. Plug in the device into the wall, plug in the appliance (lamp, fountain etc) and train it to a button. I use four in that room, three separate lights and the fountain. Life is easy and the wife is pleased! Win Win Win!  I did look at more complex technical solutions that allow me to control things with an app on the phone. Sure they are great, but at $50 a device WAY too expensive. And to be honest, leaving the little remote on the coffee table is much easier than looking for an app. This is appropriate tech that solves my problem perfectly and at a great price.

This device has an easy to understand information screen that can give added piece of mind to those that need it. I like seeing the load the device is carrying and how much time it can carry that load when the power is out. Power goes out frequently in my area and this thing has worked flawlessly. Our power usually only goes down for several seconds before coming back up so I have been able to just forge ahead as if the power was never interrupted. A worthwhile investment!

This is such a cool product!  It is getting harder to find compressed air at gas stations at all, much less for free, so I decided to get this for emergencies.  I only tested it to see if it worked on one tire, so far, but was really impressed!  It is smaller than the picture looks, and stores easily in the car.  It was easy to connect, and it didn't take as long to inflate the tire as I had expected.  I was able to get the valve unscrewed without losing too much air.  They recommend you overfill by 1 pound or so, to compensate for air loss on disconnection.  If this item lasts even a year, I will consider it a really great bargain!  I feel so much safer knowing I have this with me, and don't have to go searching for a gas station with air!  I will not dread the low tire indicator light now!
