I use this to control my heart rate with an app. What I like most about the product is it is movable so if it's ever in my way on the handlebars I just tap it and it was out of my way

I bought this because it was described as being fairly indestructible in that it won't dent, which seems to be true.  It doesn't dent, is very easy to move around on when I want to move and on the occasion that I roll off onto the carpet, it is also easy to roll back onto.  The only complaint I have is that the mat has to be repositioned quite often - almost once a day!  The description said this was not an issue, but it is for me.  The room I'm using it in is quite small, so it's annoying to have to pull the chair off and practically out of the room to put the mat back where it belongs.  I've had it for around a month and that is my only issue with it.  Overall though, I'm satified with it.

I like it being collapsible and the generous size. The reason i gave 4 star is that when i try to use its full capacity i have to use both hands to unfold it. There is a little amount of water stand at the bottom rim. Not a deal breaker to me though.

I really like the product. Its pretty good because I don't have to worry about it getting wet by the rain or when I'm doing the dishes (main reason why I bought it), The only two mini complaints from me is that the headphone adapter doesn't fully stay in (it does most of the time but a few times it comes out just a little) and that I kind of wish that the stand was made of a stronger material to keep it in since mine broke off and i'm having a hard time keeping it in and not coming out when I try to have it up.

Even though the product claims to be reversible, the brown side has a size/manufacturing country engraving on it, which makes the side unusable.

I've had the belt for over a year now, and it started showing its age about 2 months ago (two sides of the leather starting to come apart at the bottom edge, about midway through the belt's length). However, I've used the belt quite extensively, so I can't complain much about that.

It's a nice product overall, but only if its "reversible" quality is not one of the main reasons why you're buying it.

The product is convenient to mount cell phones and other devices, however, it does not rotate.  it is stationary.

The product is great in terms of speed and compactness.

USB cord is kind of short, but this is not a big deal at all and it makes sense (fits in the hard drive bag). I wish the drive had a grippy surface - it has feet but they're not great. I also wish the bag had some padding and wasn't as smooth for the same reasons above. I'm just really afraid I'm going to drop this thing or it'll fall off something.

The only issue I have with this product is the ear clips can easily become dislodged from the even if you are not moving much other than that I am really enjoying this product.

The product is great in design and usability. The suction is not that great.

The plastic handle that rotates to move the colon up and down is a bit flimsy. It should be made of  metal, not a plastic material. The instructions were not very clear. It could be a problem of translation into English. Overall I'm satisfied with the product.

It's a simple enough product. And after using it about a month, I'm happy with it. I wish it came with a pouch to carry the extra connectors. And you have to be careful to pull both ends at the same time. Don't just pull one side out or you'll have trouble retracting it. I did that the first time and had to snap it apart to fix it. It snapped back together easily enough. Then I noticed the sticker that shows you have to pull on both sides. So no problems after that. I guess it's good to read the instructions.

I like the materials that the stand is made of.  It's very light yet durable.  It's great that you can adjust it for sitting or standing.  Because I'm 6' tall, I pretty much have to put the stand to it's maximum height.  So, I don't think it would work for anyone taller than me.  It's definitely comfortable to use and to stand at.  I like how I can use it anywhere, even in areas with very little space.  I live in a small apartment so I can set it up just about anywhere.

There are only a few complaints I have about the product.  First, the higher that you crank the stand, the less stable it is.  It's stable enough to hold my laptop, but when I have it on the highest position, I have to hold the stand when opening my laptop so it won't fall over.  That doesn't happen when I'm in the sitting position.  The other small complaint I have is that screwing in the top platform that holds the laptop is not always the easiest.  So, it's better if you don't have to take it apart all the time.  But, because I live in a small space, I have to disassemble it every day.  It's not so bad, just a minor annoyance.

Overall, it's a really great product and I would recommend it to anyone who is looking for an inexpensive solution for sitting and standing with a laptop.  Those sit/stand desks can be really expensive.
