Very useful and convenient - but some buttons will fall off over time over usage
581781
In general, these are great and we've bought a bunch of them ... but a few of them, after a few months, some of the number buttons would fall off (maybe too much use?). Convenient though and they're cheap enough to replace when they fail.

This was a great case when I first got it, but the belt clip quickly lost its "spring" resiliency and became useless. I've since resorted to using the sewn-on belt loops (which are a very nice touch) instead, but the clip was much more convenient. The case itself fits my iPhone 6 with a somewhat bulky case on it well (not quite as big as an Otterbox or similar). When I had a smaller phone case on the phone it was definitely loose in the belt case, but still worked fine.

I ordered this laundry hamper because I needed to make laundry less of a chore. I appreciate that I am able to sort my laundry as I wear it rather than all on laundry day. The ironing board on top has maintained its shape and doubles the usefulness of the hamper. I have owned the hamper for almost a year and have started to notice it is becoming a little wobbly because some of the plastic separation pieces between the rungs which span the length of the hamper and the upright side bars have broken. I am hoping tightening the screws without putting new plastic inserts in will solve this issue.

I've used a number of different brands of portable mice over the years.  This Belkin is definitely among the nicer, with one caveat: I find they aren't quite as durable as some others.

The mouse tracks well over a variety of surfaces (glass table tops excepted), the track wheel rolls smoothly and the buttons start out with a nice degree of resistance.  The cord reel is less prone to tangling than some others.

Unfortunately, I find that after a few months of riding in my bag, the buttons start to get jammed and are increasingly hard to click.  I admit that I am not as careful to prevent rough handling as I should be -- and if you're careful to keep the mouse off the bottom of the bag, you probably won't have this problem.  But while they last, they're good enough that I overlook the relative fragility.

The aesthetic on this case is fantastic, and it seems very durable -- it could take a good knock on the corner and the phone would come out fine.

The only drawback deals with the side buttons. First, it took about an hour or two of fiddling with the phone at first (perhaps loosening something up?) before I was able to get the volume rocker to function properly. It still seems a little bit skewed... as if the button isn't lining up 100% or that the rocker doesn't have full range of motion. Second, the power button seems to be very easy to accidentally hit -- not a huge deal, but it was a little bit more difficult to accidentally turn the phone on without this case.

Overall, I like it a lot and there aren't any cases I would prefer over it. It adds nearly zero bulk and slides in and out of the pocket very easily.

Edit:

After a few months with this case, unfortunately it broke. The weak point was near the battery, where the shell around the perimeter of the case is at its thinnest. The case broke at this point, leaving the metal perimeter to fall off. Without that perimeter, the buttons are unusable and the case is effectively useless.

I liked this case while it worked, but that was a lot of money to spend on case that wouldn't hold up for even six months.

Bought this because my keys kept falling apart. Does the job of protecting my keys, buttons work just fine with this in place. Easy to put on, but after a couple weeks' use it still fits snugly, keeping keys together.  For some reason, it appears cheap to me, not very pretty, but very practical. Packaging included strange unprofessional grammar, odd but doesn't interfere use of product. Works, would recommend, but not overly impressed with appearance.

These have a few issues staying fastened, but overall they're very convenient and worth rehooking them here and there

This is super convenient for being mobile and incognito. I use this to weigh the dandelions I pick from my back yard and consequently share with my friends. Boy, this is quite useful; the only downside is the buttons don't light up, so it isn't NEARLY as discrete as Id like.

We've had this remote for almost 2 years now, and it has been great almost the entire time. It's easy to set up and customize to your system, and with minor exceptions, it does what's it's supposed to do (turn everything on and/or off at the same time) with no issues.

In the past month or so, however, we've noticed some problems. The charger is very finicky, and you do have to make sure you've placed the remote on the charger correctly before walking away. 9 times out of 10 it's fine, but sometimes it's placed wrong. That can be said of any rechargeable device though. Occasionally, we clean the contacts on the remote and the charger with alcohol, and that has definitely helped prolong the life of the device.

Another issue we're experiencing is that the Volume Up button does not quite work - it either fails to respond, or actually turns the volume down instead. It's very frustrating, but I think it's due to user error rather than the device itself. Since some of the buttons - and the space between them - are so tiny, I think that debris might be getting trapped in there, causing the buttons to malfunction. We've cleaned the remote with compressed air in the past, and I'm going to try that trick again to see if something is stuck under the volume button.

This is an expensive remote, and it deserves to be taken care of if you expect it to function correctly. You can't beat on it and you need to keep it clean. But for all the convenience it adds to your daily life, I don't think that's too much to ask.

Very useful, I use mine daily -

Only issue (and I bought 2 and this happened on BOTH) - is the little slider that opens a ventilation hole is cheaply built and comes off. That aside, it's a great asset to your kitchen!

This key box works really well and it is a great idea; however, the plastic buttons break internally leaving the key box innoperable. I have two of them and one had to be removed to be opened and now the other one is having the same issues.  I now keep a spare key in our main key box so I can open my shop if the lock box breaks again. This began to happen after about 1 year in operation.

EDIT: After about 6 months of regular use, the left mouse button broke off. I'll try fixing it with glue, but whether it's repairable or not, this is no longer a five star product.

No complaints! 5 Stars.
Side buttons are easy to press
DPI can be switched quickly
Cool lights indicate current profile and DPI
Customization is very easy
Background process is lightweight
Comfortable in my hand
Has 8 weights that contribute nothing but don't detract either

This has saved me incredible amounts of time. Very convenient and useful. The only issue i had with it is that the little divider inside started breaking after the first week, however, I solved it with duck take and it worked just fine.

It's a slim case that feels great in the hand. Not too slippery, but not sticky/silicone. The buttons push in nicely, so you don't have to break a finger pushing them in. However, two of my button covers fell off within 7 months. The seller, Maxboost, replaced the case for free. This really comes with a lifetime warranty :)

Good design, very easy to use. Durability may be questionable. The LED display flickers of a bit and the filter screen fell apart within 10 months use. Still, it is providing a lot of satisfaction and utility. I hope to get the screen replaced, so will update this once complete.

The rubber inside one of the arms started coming off after a year or so. I need to glue it back on. Otherwise, extremely convenient. I can get the phone in and out with one hand, and it allows me to easily use my phone as GPS or a music player. The suction has never failed, even on the hottest days and with me yanking the phone out constantly.

Inexpensive, does the job, and has a nice size display/buttons.
