“The motors on my GRi-1500LiV2 seemed to have lost some zip, I called and the technician was excellent and said the brushes may be dirty (cart has about 400 rounds on it). I asked it cleaning them was something I could do, he said if I sent them in they would rebuild them for only parts & shipping. I was blown away. That is great customer service. Removing the motors is only 2 screws, I sent them in and as promised was charged $20 parts & shipping. I can't overstate how good the customer service is from Cart Tek and how they stand behind there product.”
