Mine was done by Mr Chew in 2008, when he was still not so busy with his biz. His choices for blinds were limited at that time. Yes, he left no mess after putting up the blinds, but I don't find its quality that fantastic, just average, nothing great to talk about. When I noticed that all the plastic blinds stopper were cracked, I told him abt it on the spot, he said he would come back again to replace all of them. But he never turned up. I expected it since biz was over & payment fully made. So I used super glue to seal up those cracks. My master bedroom will have morning sun for 6 mths & study room for next 6 mths, so I only pulled the blinds everyday for 6 mths in each room. After 4 yrs, they are still working fine, thanks God. My advice is, if your want cheap but ok stuff, go for him.
