Great teflon feet replacement for mice; although it's not as smooth when you use it with a mousepad(specifically Razer Destructor) but it's good for hard and smooth desk surfaces. I think it'd fare better on a metallic mat. I think RM17 for one set of teflon feet for my Logitech G9x is a bit steep considering I could buy ones for the Razer Imperator at the same price and get two sets.

Express postage takes only 3-4 days to arrive at your doorstep. If it's raining, then bad luck - your package might be a bit damp but the contents will still be intact.

Overall it's a good seller with useful products and the only person around selling replacement teflon for mice.
