Texture très agréable au touché; ventouse super adhérente mon esclave à apprécié, très bonne qualité. son diamètre convient pour des habitués et pas pour des débutants.
Whilst these might seem quite expensive and might not get too much use the feeling that they produce is amazingly intensive and I only have the 5mm beginners one.
It take a bit of experience and you will need to but lube and cleaner once the couple of sachets included are used.
That said a first timer should take it carefully and slowly and don't forgot that you could be in for a nasty shock unless you insert it first then switch on the power. Take it slowly until you get used to it.
