"Great customer service as far as I am concerned. Had an issue that had really nothing to do with the seller but they played the middle man game and took care of ot for me. Very happy with my purchase all around."

"The basket is great. It fits my Genuine Buddy 50 scooter. I had to modify the attachments in order to put it on my back rack. I used an angle grinder to shorten the bottom pieces to fit up under the back rack. I can carry a gallon of milk and some miscellaneous groceries in it. I do use a bungee cord across the top so nothing can bounce out."
