Bought this about 18 months ago. Recently the big screen has picked up various marks *inside* (i.e. not scratches but apparently some kind of manufacturing defect?), and the strap seems to be wearing very quickly. On top of that, a week ago the main display went dead. I believe this is simply due to a battery running out, but given that my old classic Casio had batteries that would last up to 10 years, this is not exactly impressive.
The massive chunkiness makes it very difficult to roll up your sleeve and read it, and it's appallingly difficult to read at night.
On the whole, I wouldn't buy a watch from these guys again. It's very much style over substance.
