I bought it as a cheap solution to inspect my fuel pressure temporarily. It gives nothing even close to resembling an accurate reading and after a couple days the backing split and it started leaking fuel. In the process of removing it the lens popped off and I got sprayed with fuel. The lens was deteriorated and fogged up due to contact with the fuel. Guess thats what I get for not being patient but I will expect to have the $18 I payed for it returned to me
