these are picture from my very old (but still working!!) 901H ... but i added the same rubber pads on the back and the side pads to the 901s also (had to make some cut outs with a sharpie for the power connector and the smart card reader)
have added some anti slip pads at the backside and some rubber srips on the side
that protects almost as the complete closed silicone thingy ... does not slip on the table anymore and has a nice feeling in the hand now
Thats a good ideal but it was not easy to produce.
We think if we build a product for our customers, it must be a good product that allow our quality standard. if not, we will not produce that product. sadly that we have not find a manufacturer that can produce this case.
If we have any new accessory for our product we will send here at first.
