Read before purchasing anything from SGS. They will NOT issue a refund, if you look at their returns information site you will not find the process on how to return your goods. They mention a 60 day return policy but will find any way of getting out of it. I purchased and tested a Milwaukee tyre inflator that didn't meet my requirements however as I had opened it the item did not qualify for returns. All the packaging is intact, there's not a mark on the item and is in re-saleable condition so what's the issue? The after sales customer service is absolutely terrible and lacks any experience. I've been in the trade for over 16 years and never had to deal with such a terrible company. Extremely disappointed and will not be doing business again. Go elsewhere pay a little more and get proper customer service.
