Ads often don't list crucial information to satisfy a decision. Several things I'd like to buy, but I need to know measurements, specifications, materials etc. For example I ordered a "super bright" 100w LED light. The ad doesn't specify the lumen output, a measure of brightness. I get a 40w 3550 lumen product. Not what was described and 3550Lm is not bright at all. They have real inventory management issues as well, everything is just about sold out. I don't want to buy the last of a supply of an item after all the good stuff is picked over. The boxes for the lights I ordered were all crushed.
