Bests & Worsts Reviews from Amazon

I was looking forward to a way to reduce plastic use and saw these in my Facebook feed. I was so excited to try them. #1) They're a little spendy. But seeing how they're reusable, I can negate that. #2) The smell is very offputting. #3) They did not come with instructions, except to go on a website to learn how to activate them. #4) Tried it, but it didn't stick as well as I thought it would. Bummer. I'll keep trying to see if it will change my perspective.
