I use a Cottonmouth NP - $9.95. My only complaint is that the cord is too short and I had to lengthen it so it would fit when attached to my PFD. Maybe they figure it'll go on a helmet... Another NP is Smileys - also $9.95 and it looks similar to the Cottonmouth.

well I bought what ever I could find online. Smiley's I thought was junk. Piece of metal that you can bend or open to adjust pressure. Plastic against your nose is hard and uncomfortable. Ccessi was better but still wire and plastic was very small but more comfortable. Zoggs was the best with plastic clip with the proper pressure. It also has two larger silicone pads for your nose very similar to Tweakers. Only con is no line in case it pops of your nose but it holds very well and is comfortable. I guess you could make a small line up to prevent loss of it. To bad Tweakers are gone with everyone looking for them when I did a search on line.
