I have only two minor issues, but never bothered HAL with them. Small accessory items. Figured for all HAL has saved us, my minor loses are minor. Can say the issues were not Hal's fault directly, but oversight on my part.
Have ordered several, repeat several thousand dollars worth of merchandise from HDL and only had two problems. One was a tire that started to separate after 3,000 miles, shipped it back and a new one magically appeared on my doorstep. The other was a problem with the Markland Lighted Ergo Boards and called HDL for the phone number to Markland (never even mentioned why I wanted it, and was given the number immediatley) then called Marland and should have the replacement screws and spring clip that fell off the bottom of the board in the next few days according to their customer service folks at no charge.
Thinking about it: HDL, Bushtec, Hartco, ****-O-Peg, and now Markland have all treated me real good!
