Well I received this product Monday, it's friday and won't turn on anymore. It was wonderful for 4 days, but like I didn't spend 30-40 bucks on this for it to stop working. I'd like my money back, considering my old heating pad lasted 3 years.

Ex Output:
negative

Ex Input:
These chairs are easy to assemble, comfortable, and they easily support 250 pounds. I use these in front of a couple arcade games I have and they look great.

Ex Output:
positive

Ex Input:
Great product for my purposes. I use it (along with another Crosstour camera, but previous model) as additional camera to record action video - fast movement, deem light... - it does what I need. And, of course 4K resolution is great, gives a lot of flexibility during video editing. Camera controls are simple and easy to operate. Battery life is good, again, enough for my purposes. I recorded 2 hour of almost non-stop action on one battery, and couple 32 GB micro cards. Highly recommend this product.

Ex Output:
positive
