Very happy with the buy

Beautiful product..design is good ...I got mine spray painted so don't be confused they only come in white ..solid construction. I tried to read the instructions to open the blades...ended up popping the blades out ...no worries their are you tube videos and the company that makes them is small but very responsive...honest and helpful ...I am talking txt messaging helpful with video links being shared for tutorial ....incredible folks work there. So don't use excessive force on the blades ...they move easy but move from underneath...once set it is hard to change them ...also don't screw them to the side ...you don't need to they are heavy and sit nicely on the slot
