Processing seems a bit simple or "handmade" (for 1 star deduction), but the functionality and durability is far completely OK (after about 50 hours). Should change that, there is an update! Have the same 3 pieces ordered wg. the relatively high shipping share and all in all just under 19 EUR paid for it, that the price is acceptable for these relatively rare / expensive version. Fast delivery of "showglassDE".
