Posting a review to let other customers know: that this vendor has provided excellent customer service, they were understanding, listened and very patient. I had purchased the FitLife Nordic Walking sticks and we could not get them tightened, they tried to walk us through tightening the sticks and when they would not tighten, they provided a new set. It looked like they tested them before sending them out, which was helpful for us when we received the replacement. I purchased these for my mother who is 84 and they help her to get her walking in everyday.
