Review on 🪥 ProResults Standard Brush Head by Philips Sonicare HX6013/64 - Pack of 3 by Carrie Spencer

Bought these for the first time and they were fine. Bought them again and 2 of the 3 tips were defective - didn't stay on unit - but went through the return window and ended up with a very expensive tip. Bought this again and they made the brush heads so tight you have to struggle with that. You need pliers to pull it off. The packaging is BAD. To open it you need a utility knife, strong scissors and gloves. Gloves because the plastic being cut is so sharp and hard you could seriously cut yourself. It's ridiculous to use this packaging for toothbrushes.
