Seen these before. How do they play?

Well for what they are. You'll need your own mouthpiece though, and the slides take a while to wear in. As far as im aware they havent posted any advice on lubrication yet, so ive not risked using any! But ill be using it at a gig in a couple of hours

Considering they cost 49.95 pounds if you buy them directly from http://www.pbone.co.uk/" target="_blank and this guys going for a profit, I'd personally wait until the horns are back in stock, which happens on a regular basis.

Cheers
