Backyard Plus was great to work with. We easily found the necessary component on your web site (appreciated your verbiage that this was the only part that had ball bearings). We ordered two over the weekend and on Monday received notice that they had shipped. Provided videos are helpful if needed and the price was competitive. Thank you for a great transaction…will use again if necessary!On 01/15/2026 by J. O. (verified customer)
