Listen to the 1 star reviews, works great for about 5 minutes

Appears to work for about 5 minutes then disconnects from your heart rate monitor, speed and cadence sensor and then shuts itself off. iPhone apps are able to maintain the connection with the sensors but it appears this device won't attempt to reconnect if it gets disconnected somehow, requiring you to stop your bike, pull out your iPhone and re-pair the device. Used with an iPhone 6+, a Wahoo TICKR X HR Monitor, and a Duotrap S speed and cadence sensor.

A friend of mine recommended this product and so I got it before taking a trip out west.  The installation went well and it seemed to work at first, but after about 5-15 minutes things started going wrong.  The music would just go out for no reason while I was riding.  If I clicked the buttons it might come back on and it might not.  I didn't want to fiddle with it since I was on my bike, but when I stopped I could get it to work and then it might work for half an hour.  In some cases, it didn't even last as long as one song until it went out. After the first day I thought I had it working, and the second day was not too bad, but the third day it was a total bust.  I couldn't get it to work at all.
That's the bad news, and from some of the reviews I've read it is a crap shoot whether you get a good one or not.  And by the way, the price of this was $69 when I bought it and now it's almost double.
The good news is that I got in touch with IBD Electronics and they were great.  They gave me the options of replacing it (but it was back ordered), refunding my money or getting another product.  I had a couple of questions and acutally ended up calling them.  The people there were fantastic.  I eventually decided to get an LG Tone and they sent it out and credited me with the difference in the same day.  Great customer service.
By the way, the Tone is great.  I have not tried to use it to make or receive calls, but really don't want to do that while riding my motorcycle, so playing the music and listening to the GPS is all I need it for.  When I'm not on my bike, the thing works great at not only the music, but also at making and receiving calls.  The parrot device may be good for when you are on the bike,but that's it.  The Tone is great for sitting at your desk and listening to music.  Give it a look, and it's only about $40.

Like so many other 1 star reviews, mine started with me loving this item.  But, just after the return window closed, I started having the same issues so many other reviewers experienced, except for the USB port breaking.  At least mine stayed intact.  After a month, the device started refusing to connect, or stay connected, to both of myAndroid devices.  It also started chattering after 40 minutes or so of continuous use.

Finally, after restarting it and one of my Android devices about a hundred times to convince it to connect, I finally threw the POS across the room and experienced another common complaint in reviews.  The ear pieces are attached with a teeny tiny minute quantity of plastic, instead of a snap fit so they can be reattached if they come off like every other headphones.  When mine finally broke, I finally had the excuse I so badly wanted to just chuck the piece of garbage in the garbage where it belonged.

Bought two sets of  these a while back. I finally put them up today and they worked for about five minutes each and then quit working. Do not purchase these. And if you do, make sure you test them right away. Thats almost $30 down the drain for me. Junk!

Stopped working after a whole 5 minutes :/
Save up your money and get an actual humidifier.

What a piece of Junk!!!!!!!  Worked great until it was too late to be returned then one day while using it, it just shut off.  Tried it again later and it worked for a minute, then shut off again!  Sat for days, checked it all out, not plugged, filter clean, turned it on, worked for 5 minutes, then shut itself off again!!!!!  What are you supposed to do with a vacuum that only works for a few minutes at a time?  After reading other reviews, this is not an unusual problem.  This is the second vacuum cleaner that I have had trouble with, that I have ordered from Amazon.  At least the first one had the decency to quit right away.  Trying to get this one to a service center is probably cost prohibitive.  If I had bought it from a store, I would have a person to complain to face to face;)  Save yourself the grief, buy something else, unless you can get your floor entirely vacuumed in 5 minutes or less!

This little gem worked flawlessly... for about 5 weeks.  We probably used it about 15 times during that period and plugged it into the charging cord each night.  Yesterday morning it was totally without life.  No lights, no sound, no pairing, no connection... completely dead.  I am guessing it probably is the charging port which seems to be the bane of many Bluetooth speakers. We had the same problem with the Amazon Basics Bluetooth speaker but that was after using it for well over a year.  I contacted Amazon about returning this item for replacement but it was outside the 30 day return window.  They suggested checking with the documentation that came with the product for warranty information.  Of course, I don't have that because it was working like a charm for the first 30 days and my place isn't big enough to save every box and multi-language manual that comes with every device I've purchased over the years.  Live and learn.

It worked for about 5 minutes then stopped. I changed batteries, that did nothing. I have a Jack Russel and she didn't don't destroy it, it just stopped working. Sending it back today. Will try a different brand

I got this camera from a vendor on eBay about 5 months ago.  It came shipped directly from China, which appears to be the case with most of these sold on Amazon, as well.  Keep that in mind, because when it comes time to return this thing (which will happen), that will severely complicate things for you.

The lights on the camera really did not make very much sense.  But at least it worked.  Don't even bother with the instructions - they are almost completely useless.  Just take an hour to figure everything out by yourself.  Hint: You need the remote to change certain things, such as which video feed will be the main video in the LCD screen.

The quality wasn't awful, but it wasn't good.  The only good view you'll get from this is during the day, from the front-facing camera.  The rear-facing camera's quality is on par with that of a low-quality VHS tape.

This camera felt incredibly cheap, but it worked adequately for me for about 5 months.  Until it failed for no apparent reason.  Now one light comes on, the screen never comes on, and there isn't anything I can do about it except buy another camera.  This is a really good concept, but the quality is just not there.  Spend a little more money on something else from a reputable manufacturer.

Setup was easy,it worked right away, and the sound was fine for regular TV. However after about 5 minutes of use I hit the mute button - but then it wouldn't unmute. Nothing on the remote worked again. The remote display seemed to behave correctly, but the soundbar didn't register anything. I tried a million different things, even tried new batteries. Nothing. I'm done with it.

Disclosure: I bought this unit at my local warehouse club, it's going back tomorrow.

This rope felt great for the first 5 minutes of use, but then it split in the centre of the cord. I ordered two, and did not want to open the other package in case it was of the same inferior quality. Save your money and ignore the reviews here and on on YouTube. This is my first one-star review, and I hope it will be the last.

i purchased these 1.5 month ago, it did a fair job in grinding, and although cleaning was sorta messy i did not mind. i used it almost everyday, at least once a day. however, this thing stopped working all of a sudden after approximately 1 month. i know it's cheap and i did not expect it to last long but 1.5 month is a ridiculous time for such thing to happen. pay a little more and get something to last longer.

Worked for 5 minutes. Don't waste your money. I think 1 star is too much...

Worked great for about 5 weeks of constant use, was pulling about 80W, never got hot to the touch or had any noticeable voltage swings. The issue is that it completely stopped working after about 5 weeks and now produces 0V output, regardless of the connected load. It was connected to a surge protector, and other items connected are still working fine, so it seems to have self destructed. Outside of the Amazon return policy length, so now it goes in the trash.
