What you'd expect for $15

For the $15 I spent on this, I guess I got my money's worth. Unlike the picture that shows it as a roll, it came folded up into a square. So now it sticks up under my sheet where it was folded. I think if it came gently rolled up, it would be a lot squishier and sit flatter on my bed.
I have a regular twin bed in my dorm, and this isn't long or wide enough to cover the mattress. It does make my mattress more bearable to sleep on though. It's definitely nothing compared to my roommate's memory foam mattress cover, but there's no way I'm spending that kind of money.
Overall, it was worth it for the added comfort. Plus it arrived in less than a week.

Pretty good, but not very original.  For the price I can't complain.

They work pretty well for something that was only about $15. Easy to use, battery life is somewhat long. However, they have a very short range. I was only able to get able 1.5 to 2 miles of distance between the 2 walkies before reception became spotty. Overall, it's pretty much what you'd expect for the money.

Price = expected quality.  Good but remember what you pay

It was ok for the price, I suppose. Keep in mind it is merely a toy, so don't expect any great craftsmanship or technology.

Not bad for 15 bucks.  A couple of design changes would make this better but for the money it'll work for my needs.  The glass is held in place by one screw near the base and suction cups on the Y/shelf support.

Not great.  They are cheap Chinese knockoffs, but for $10 you had to know that.  It functions, and does what it's supposed to.
If you have reasonable expectations, then for $10 they are a good deal.

Does what it's supposed to... Better than buying the same thing for $15 at a big box store

Not the highest quality, but good for the price.

For $15 let's be realistic, it's a flashlight that serves a purpose and comes with a free battery but it's not build like others costing $50.  No thumbnail screws to make attachment and removal quick, it instead uses an Allen wrench and two screws. When attached to a shotgun rail the unit spreads wide but then the light assembly wobbles, so I will probably fashion a piece of rubber or electrical tape shim.  It's an expensive functional light but for those who want an expensive high quality unit don't buy this and then post negative comments. It is what it is and I'll be keeping mine.

Item is relatively cheaply made, but TOTALLY as expected from a $15 watch. It works and looks nice. Thats all that matter as of this point.

Ok for it's price. It serves its purpose. Can't complain- you get what you pay for, but it's not a total bust.

meh quality, what I would expect for price, however.

Good movie.  Maybe 3 1/2 stars. Certainly worth the $15.

Overall this was a Good buy for $15. I bought this to charge my iPhone and my camera batteries while camping. I had already purchased the Starter set for about $50 (Black & Decker VPX903X1 Li-Ion VPX Starter Set with Power Screwdriver, Cut Saw, Flashlight, and VPX Battery with Charger) so this made the most sense as a portable charging option. I need to do some more testing but it seems to work well enough and I don't have to set up solar cells or use a hand crank. Had this come with the starter set I would be much happier. The quality on these products seem pretty low, but at the discount prices it gets the job done.

First off, it works. It will attach to your bike. However, you don't get much more for your $35.

The material is fairly cheap, though some parts, like the tab that closes the case have some sort of vinyl instead of the mesh. There isn't any padding. It is isn't waterproof or water resistant. It is just what it is. For $15, I'd give it a great review. For $20 I'd give it a good review. But for $35, I just feel ripped off. Bottom line, if you had any gumption whatsoever, you could probably make something similar that wouldn't be much worse (or better) than what you have here.

Edit: A few more thoughts after using it for a month... First of all, I'd like the straps to be longer. The unit is designed to sit on the front of handlebars, but that area on my bike is too crowded. I attach it instead to the handle bar post, facing me, but the straps just barely make it. It would also be nice if there were more ways to attach the unit to the bike. Maybe that means more straps on other areas of the case? Anyway, it would be great if this was more versatile. And yes, the jambox buttons do get pressed in on occasion, so some sort of solution to that problem would also be welcomed. And one word on the sound. The jambox is great when not moving, but when biking, the sound decreases substantially. You'll still hear it, but if you're like me, you'll kind of always wish it was a bit louder. Obviously that has nothing to do with the case, just an FYI.

Get what you paid for. It's a good product.
