Note: Im giving it 5 stars for durability despite having broken one or even possibly two sets, since the breaks were entirely my fault. I am a size 8 shoe, all the time, and they fit perfectly. But it does work just great, and it prolongs the life of your sneakers or boots. matches all my decor! Why did I only give it 4 stars? Well, mine did not come with a charger, just a cable and the stand, otherwise its 5 stars. They eventually promote their expansive (£2,99/month) premium feature but it does not do much for the price (basically, with it you can setup a home address to be notified if tiled product is away from it etc. The plus side to it being a heavyweight is that it stays where you put it and is less prone to vibrate the surface it?s on. Got the 8 and I couldn?t be happier ! This toy is really good, my dog loved it and I would really recommend to anyone with a destructive dog who usually chews up all soft toys within an hour. If they were to be second hand, I just would have like to know.
