Also.. btw. Just to make fair reviews, consider the whole, since you chose to try the whole after reading the description. (being their means it matters to us and might be repaird or enhanced right next. Maybe before caring for my health. If you would review a 100-in-1 swiss multi-tool, you also wont stop after the first one. Then you still cant review. (or it might be mistaken/unintentionally harmful. (yet the effect of an angry 1 start. might surely amass to a 1000 users less and fewer voluneer urs when we are 99% "understaffed" )...
