Blind parts by Dave gets 5 starts from me! Easy to use web site, good availability and exceptional package departure. The bad…. after experiencing some intermittent trouble controlling my blinds due to a large coverage area, I decided to upgrade to the Pulse Pro model instead of installing a second Pulse (regular model). The coverage issues are now behind me as the Pro has a larger coverage area but also REMOVES THE “Set upper and lower shade limits” feature. Very disappointed!! I do not recommend this upgrade or in my opinion, DOWNGRADE. There are other vendors like Bond so do your research as they don’t always advertise what they are removing as a feature in a supposedly higher end unit.
