I've had a couple of these, a very flimsy green one from Ebay that lasted one season, and a much sturdier Gardman one from a garden centre that has just started to split after 2 weeks [Grrr!]. Tried various sticky tapes on the old one, and found that the silver waterproof Duck tape was best. If you can afford the genuine stuff I wouldnt bother with tape from pound shops or Ebay as some are rubbish, and you won't know until its too late!
