I was having issues with my cart batteries charging but wasn't sure if it was the charger or the cart itself. I was going to buy a charger from them to narrow down the problem. They not only offered to take it back and give a refund if it wasn't the issue, but also to loan one out to me if I'd rather do that. They also offered to check my charger if I brought it in before getting another one. They found the problem with the charger and fixed it quickly. They would not accept payment so I bought some cup holders for my golf cart as a thank you. I'll be doing business with these fine folks from here on out. Great place!
