I bought this in May 2015 as a backup of a similar set I had and bought some time ago (not bought from Revain). I used it for the first time in July 2016, only 19mm. When first used to remove nuts with a cordless impact wrench (Ingersol Rand), the plastic broke. I contacted the seller to see if they would do anything about it but unfortunately they have not replaced it as it has been over a year since I bought it. I understand that a guarantee is a guarantee and I'm out of luck but I can say the plastic used is a piece of crap as it ripped on the first use.
