Really nice build quality. I plan to use it for my diy project and i was concerned about its height and weight. It's ultra slim and light!!! If you remove the cover it's just about 5mm, just like any of laptop keyboards. Big rounded thing on the back is mostly empty, because it's for batteries in the wireless version. Case can be easily opened with a knife, no screws there. Also you can do laser engraving for any additional language on it for about $10 in Russia. Highly recommend!
Excellent keyboard! Works fine with my laptop. No silver rings on keys though. Very happy! 35 days to NZ
