Nice but short range and battery life
349597
I ordered this remote 3-4 months ago for my Canon Rebel T3i. And it works sporadically. Sometimes camera will recognize the IR signal instantly and if I try to use the remote again from the same position then it does not work. It seems that the range of this remote is very short (about 6-8 feet) and it does not always work even from that short distance. I'm not sure if the battery in my remote is already weak. In the description it said that battery will last at least 2-3 years but that's not the case. I am not a heavy user of the remote function so am still surprised at battery becoming weak after such a short time.

Worked well for about 11 hours, then the range dropped dramatically! After reading a few reviews I concluded that those 5 or 4 star  reviews were typically made as soon as they used them and not updated overtime. During the time that the range did work well, the battery life was about 5 hours and sound quality was pretty good.

Battery life couled be better than it is and it is slow to connect to WIFI.  Have a slight hiccup in the upper left corner of the screen.  Otherwise works like a charm.

just ok. its nice not getting tangled up in wires. its kind of a pain to pair sometimes. the battery life isn't great and you cant go more than about 10ft (not even close to 10 meters) away from your phone, iPod, etc. before it disconnects. Im not trying to go to the moon but it'd be nice if I could walk to my printer without having to turn off or pause my music or take out my ear phones.

These things are just ok, at best.  The 150ft range stated might work if you are somewhere in the wide open spaces without walls or anything around you.  I usually have to be on the same floor in my house to see them through the app interface.  Overall I have no issues with the app itself on my Andoid, it works well.  The issue I have is the device itself.  The beep is not very loud and you really do have to be close to hear it(which kind of defeats the purpose of trying to find your thing you have lost).  Also, there is no low battery indicator on the device.  Recently I tried finding my son's care keys and I pulled up the app hoping to get s signal(we knew they were somewhere in the house).  I walked around and never picked up a signal through the app because the device was offline.  Well, it was offline because the battery died.  We eventually found the keys on our own.  So I bought a pack of 2430 button batteries and replace them in each of my 3 devices every so often to avoid the dead battery dilemma.

I've actually only used it to find my lost keys once.  I was an idiot and left them in the garage actually was able to use the app and device to find them.  I have never tried using the crowd around GPS feature.  I am hesitant to think it actually works well unless you have a lot of people in the area where your thing is missing just happen to be close by it.

Overall, I rate these as just ok with a generous 3 rating.  Keep your expectations realistic of what you will be able to do with it

Great price and battery life is more than i expected. Range on them isn't that great, but good enough for my use

I was very impressed with its sound quality and battery life.

Only negative is the range isn't that good.  Roughly 15 feet, and less if there's a wall.

Works great in your pocket.  I'm not sure I'd run with it, but you can play tennis/racquetball without it moving around too much.

I like how simple and easy to use this little gadget is.  The more I use it, the more I get a feel for how far I hit my clubs which is useful if I don't have a gps/rangefinder on me.  My only problem is that the battery life only lasts about 23-25 holes.  I have to charge it every night and that's something that I really don't like.

The screen is really nice. I like the Microsoft health companion app. Cortana integration and text/email notifications are really nice too.
The biggest con is that the GPS isn't very accurate. Seems to be anywhere between .25 and .5 a mile off. It's not a problem for me since I use my phone for the GPS.

Battery life could be a bit longer but charges fast. I get about 2 days of charge and charging time is an hour or less.

I was very happy with the quitenes of this clipper but the battery life is too short. I can only use it for 10 min after 24 hr recharging period.

Not great range, but much better than having to run using a self timer.  Battery didn't last long and it was hard for me to find a replacement of that size.

It's very intuitive to pair with my phone and they are decent earbuds as far as sound goes, but the battery life is really short. One really has to charge them after each day's use.

Excellent sound and Bluetooth connectivity, but battery life far short of estimate, more like 2 hours at best. Suggest looking at an alternative for longer battery life.

The range is not as strong as it describes.  The batter life is very good and charges usually within an hour.  Great ratings and overall good sound quality.  Volume is extensive.

Low battery life (5-10minutes) after two uses with full charge. Really small Bluetooth distance, more than 5 ft and it begins to lose connection

Bluetooth range poor. regularly have to re-syncronise with phone.  Battery just about lasts one working day. Otherwise , good screen nad good apps.

Pro: extends far and works amazing in the dark. Small and light to carry around

Cons: short battery life, requires to plug into outlet. Doesn't hold a charge.. I have had it plugged in for a day and a half and it still shows  not fully charged. Would prefer to be battery  operated . The charging cable doesn't seem to even fit all the way inside. The power on it doesn't last long enough for a full hour.

I rate it a 2 only because it's awesome when it works but not long enough for more than 30 min
