Wrote a review recently to say good delivery time, good product - my order was for just over£40. However there was one glider short which caused wonky scratchy problems. I emailed Chris at vital parts and had received no response whatsoever after one week. Having given a review on line to that effect I received 4 new gliders by the next post. There was no letter or message with them just a package with 4 gliders (thank you, but I only needed 1 which as explained I had already purchased from elsewhere) - however, surely it is good practice to add a note to say herewith 4 gliders sorry for error hope this sorts out problem, or something to that effect!!!! I wonder what would have happened if I hadn't reviewed the product on line - would Chris eventually have answered my email - who knows. My advice is: if you have a problem with your order from this company then review on line if you want a quick response.
