Mostly functional, broke after 2 months

Super easy to get on and off. Worked well on icy sidewalks and slippery trails. They kept sliding up and over the toe of all but my widest boots. One of the rubber straps snapped after two months.

The charger worked well for a couple of months, however the top of the cable with the micro USB has disconnected and is no longer usable after regular use. The extra port still works for charging devices, but I will need to look for a new charger that allows multiple devices to charge at once.

Worked great, until it broke after only 4 months of use... the keyboard is stationary so this was plug in once and play, not rough use of lots if travel, when you shake the plug something rattles around inside.

It worked, but within two months, it also broke at the connection point. The plastic is cheap and easy to break where the metal pin slides on this knob. No other choice, but to replace it. Wish someone would make a non-plastic or more durable one.

I love the idea of this desk. It's the perfect size for a laptop and mouse, and folds away compactly. There are several flaws, though.

1) The greatest flaw is that it broke within two months. When folded, the tabletop hangs on two hinges, each with four screws. The screws on one hinge ripped right out of the tabletop. The other hinge is holding strong (which seems to defy the laws of physics, but I'm no Issac Newton). There was no additional weight sitting on it or anything, it was just folded as designed. It broke a few weeks after the return window closed, so I'll try to fix it with different screws, but this is very disappointing.

2) The magnet holding the tabletop in place is strong enough that it may impact some laptops. For example, when my Lenovo Yoga is placed too close to the magnet, the computer mistakenly thinks it's in table mode and disables the keyboard. And when placed in the same position, my MacBook Pro thinks the lid is closed and goes to sleep. The tabletop is just big enough to keep the laptop off that spot, but I fidget around enough in a full day to accidentally trigger it at least two or three times.

3) It arrived slightly damaged. The tabletop's finish had a chip in it. It wasn't significant enough for me to go through the return effort since this wouldn't be out unless I was working, but given the other flaws I've noticed I believe it is indicative of the overall workmanship.

It's possible I just got a bad unit. Your mileage may vary, but I can't return it and won't spend more money on another one, so the world may never know.

This countertop oven works well, and I use it for many things, almost daily. Had this for just over two months and the timer dial broke where it connects to the unit. so now I have no timer dial; have to use pliers to set it to always on and my own timer, as the timer can no longer work properly without knowing where zero is. Will be replacing with one that has a digital interface as I do not have a 3D printer to make a replacement dial.

EDIT 12/11/14: I am bumping my review back up to 4 stars due to good customer service. They offered to send me a new one, but my work-around seems to be holding up ok, so no need to be wasteful :-)

The waterproof aspect of this unit works great. The case itself is well-constructed.

However, the plastic part of the mount with the detaching clip broke within 2 months of use. I was attempting to get the phone out of the sleeve and the zip-lock wouldn't open (I think it had a vacuum effect as it was a cold rainy day). I pulled on is a little too hard, apparently, and the whole case broke off the base. For the price, it should have been able to withstand my attempt to open the zip-lock.

I was able to rig it back up with zip ties, and it still works. It's just not detachable anymore, which is fine for me since my bike is always stored securely and out of the elements.

It serves the purpose. But the construction is very flimsy and it broke 2 months after purchase.

Decent audio quality for the price, but cheaply made. The band that goes across the top of the head snapped in half after only two months of use. In-headphone language randomly changed to Chinese after a month of use.

TL;DR - Sounds great (within reasonable expectations), broke after <6 weeks.

Picked this up about a month and a half ago (July 2017) during Prime Day.  Obviously, I wasn't assuming that this would produce Bose or Klipsch quality sound, but this certainly met my expectations once it was (easily) connected.  I would have gladly rated it a solid 4 stars, but conveniently after less than 2 months, the problems started.  It randomly turns off and doesn't let you turn it back on unless you pull the power.  It randomly turns on when you're not watching or listening to anything, and doesn't let you turn it off unless you pull the power.  Then there's a fun part where it sometimes turns off for 30 seconds, and then turns on for 30 seconds.  You can't get it out of this loop...unless you pull the power.  I haven't attempted a return at the time of this review, so I don't know if this is an issue specific to the unit I received, or if this is a bigger issue with the product as a whole.

The spring that holds the cell phone broke in 2 months.

Worked for a couple months button stopped working.  Rubber tears over button

The speaker quality was pretty decent, but the auxiliary part broke when pulling out the aux cord after two months of use, so now you can only use the speaker through the mic jack which gives crappy quality. Kinds bummed about that, but until it broke it was a great speaker.

It broke after 2 months of use. Tried replacement but that was only for 1 month.

I bought this back at the end of August. The teeth that connect to the wire broke; I tried to show it in the photo. I think the problem is that the wire is a little loose, so the case would disconnect a good amount of times from it. It worked just fine before it broke, but it didn't really last 2 full months.

They work fine, but the plastic piece that connects the earphone to the headpiece broke after 2 months of use.
