I also bought a wand for £140 with the free glide, really just as a spare, not that impressed with the glide though, its not the same as the ones at £55 that are for sale, just a long line of small holes and mine looks a bit tatty, but I thought the wand was an ok price thats why I bought it, the glide does seem to be very well fixed on, you might need a bit of brute force to get it off David.
