Review on Efficient Squeeze Condiment Bottle by Lawei: Smart Plastic Solution by Chris Cruz

So frustrated they keep breaking. I've been using these bottles for about four months and either the threads on the bottle itself come loose and leak or the cap ring breaks like in the picture. I didn't use flavoring, I used dish soap (diluted with water) and my own lotions and serums. Nothing I've used them for was more viscous than ketchup and mustard. They were actually less viscous, so there was no unwanted pressure on the bottle and the contents couldn't react with the plastic. I do not recommend.
