Pros: Excellent value for the money. No wire harness attached to the chest. Work like a charm. Small and no one knows you are wearing one, looks just like a plain watch. I bought 3 for my family and they all worked like they should. Highly recommend to anyone who wants to monitor their heart rate all the time like me.

Cons: Won't work on my wife for some unknown reason. Skin voltage, skin conductivity issue? Works on everybody else! My wife does have cold hands and feet all the time. Maybe this is temperature sensitive? Tried wetting her skin slightly but still won't work on her.

Pros: None

Cons: Felt like a piece of paper, cheaply built. Arrived DOA. Charged for 2 days, will not take charge or hold charge let alone charge anything plug into it. Total piece of junk.

Pros: Nothing

Cons: Unit died right after warranty. Sony is no longer made in Japan, instead it's made in China. Phone won't take charge and won't turn on.

Overall Review: Garbage

Pros: none

Cons: 2 channels went out after a few months of use.

Pros: This unit didn't come like the last one which looking like someone fished it out of a dumpster. Appearance is decent as refurbished unit.

Cons: Everything else. Unit came with a dead battery and the wrong power adapter so no way to charge or test it. By now, it is very obvious that Asus" claim of PROFESSIONALLY refurbishment of these tablets are lies. They just throw them back in the box and resell them as is after customers return them. Two in a row DOA. As professional as the sewage oil, dead/deceased pig and toxic industrial grade pig oil sold from Taiwan to the rest of the world for human consumption!

Pros: No pro, all CONS!!!!!!!!!!!

Cons: DOA, won't turn on, won't charge! Don't believe the CSR rep's claim! Their tablet coudn't have gone through intensive testing! Not even cleaning was done! Mine came dead and won't charge at all. How could an unit like this had been tested, all hot air! Appearance of unit suck too, externally looked like someone had used it for a long time and never cleaned it, tape all over, stuff coming off, had to clean unit before I feel comfortable to touch it.

Overall Review: Totally lost faith in Asus now. Lost 2 retail box motherboard right at the end of warranty and this tablet is even worse.
