Helix glass, available online?

Hey RIU I was wondering are there any reputable online stores that sell the helix pipes? And if you own any helix glass, how do you like it?

a.l.t.usually has them they sell out fast, i never tried one its not my thing , id buy one if it was tho.

They seem to be a bit of "novelty" to me. I say that bc of their (most of the their products) "air ports". The little holes poked around to add air flow.

But all of the pieces I've held from them are super thick, which I think is a standard for them now. I have a little one-hitter/ 14mm slide combo piece and it's nice. I never use it anymore though.
