To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
14 November 2021 Regular white PTFE thread tape (the cheap stuff) measures 0.04mm thick. (Very Thin) Mega Tape (Gray Water PTFE tape) from Lowe's measures 0.10mm thick. (Heavy Duty) This tape is advertised to be 0.09mm thick, but it is really 0.08mm thick. That may not sound like a big difference between what it really is compared to what it is advertised to be, but that means it is 11% thinner than advertised. OK, I may be splitting hairs, but if they say it is 0.09mm thick, that is what I expect it to be. Anything less takes away stars.
I ran out of some good Teflon tape I bought a few years ago from the hardware store. I kick myself for not remembering the brand. I was hoping this would be equally good since there were so many good reviews, but NOPE… this teflon tape is VERY THIN compared to what I was using before. It’s SO THIN YOU CAN SEE THROUGH IT!
