I used them about 6yrs ago and found them very good, quality of kitchen is very good too. I had a problem with one of the drawers about a year after installing and they sent someone out to fix it straight away
We also used them in 2012. Was very happy with the service and quality. Kitchen looks as good today as day it went in. For pricing puposes make sure you check out Eco interiors as product is from same factory in Germany.
