I will not use this thing, I removed to see how deep it goes. I will x ray the whole set because I'm curious. Choosing this brand was risky enough. Also if anyone wants to buy these, be prepared to do some work prior to install even if you dodnt get junk like I did. Amazingly they measure out fine and were withing 1 gram off each other.
To be exact 6 were 805g and 2 were 804g.
