This is pretty much perfect for someone who wants to stretch their ear. Going from the very beginning up to 10mm it's great. It's so much cheaper than getting an individual one for each stage, especially if like me you're just planning on going straight up and not hanging around at any stage for a long while. I've had this kit for about... 2 months now and I'm up to my 6mm, going up to the 8mm next week. I did go from the 1.6 right to the 4mm simply because my ear would let me do that HOWEVER it is recommended that you leave 2 weeks between each stage from 1.6 - 6mm then 4 weeks between each stretch from 6mm+. The picture doesn't give them much justice, they looks a little cheap and tacky on the picture but in real life they look lovely, in a shop you'd probably pay £2 - £3 for one of these so they're really good value for money.
Anyways, very good product, worth it if you're just planning on going straight up.
