Excellent customer service. Excellent product, as I have had mine for four years with no problems. However, the GO++ will not get you the 45-60 miles on a charge. The best I have ever gotten was 32 miles in the summer on a flat trail with no wind. This was an experiment as I was getting 25 miles on the hills. In the winter, the battery has less range. I like the product very much and have bought two. When buying the GO++ I suspected the 45-60 was an exaggeration, but did not realize how much of one it is. That said, when I went to buy my second one, I could have bought local in Seattle, but chose to stick with Swytch, even though the battery is not as advertised, so, yes, I like the company.
