[Q]: Although good quality product, it doesn't fit my ear at all. None of the sizes fit comfortably or snug. I can't use it at all and just wasted my money.
[A]: Negative


[Q]: I've bought several air beds from various manufacturers. I bought one identical to this one 1 1/2 years ago. It was comfortable but lost air after 3 months. I justified this as the user may have not taken care. However, I now believe its the brand. This one would not inflate at all. I will not buy this brand again. I've had great life from a better brands.
[A]: Negative


[Q]: How is this thing awful? let me count the ways..First off, it took an unatural amount of time to get here. Whatever, that happens.It feels super cheap. When you handle a good memory foam pillow, it feels heavy and cushy in your hands. This thing feels like a piece of hard styrofoam. It barely squishes at all and has no 'memory', it is simply a very dense foam pillow. It's not even really a pillow- It's so hard that I cant even use it for propping my back whilst reading.On top of that, their terrible return pollicies make it not worth returning.DO NOT BUY! Just use the styrofoam your new computer came in.Ugh.
[A]:
Negative
