Just received a Pure Wand, have only used it three times. The closest to the Amethyst I have is a Gold laced G, so my experience is somewhat limited.
The Gold G will provide more stimulation to my prostate due to the texture, not much but still, it just feels better with light thrusting. I can provide lots of pressure when needed/wanted.
The Pure Wand provides incredible pinpoint stimulation, right there with little to no effort. Like someone said "it's like a P/G spot magnet". I like the small end for light thrusting and probing around. The large end is very filling, but it seems like I get less stimulation, I am thinking it is due to lack of room but not sure. Like I said need more time with it. The Pure Wand is by far the best when playing with temperatures, hold temp longer. Also works great as a massager for firm deep tissue care.
My wife does not seem to care for the Pure Wand, she does not like the weight. I do feel that if she was to use it herself (only had me working it) she might like it more. Although she does not like firm G spot stimulation she does like firm pressure on the A spot.
Plus if you did happen to damage the stainless it could be repaired.
