I found these on Ebay from a seller in China for .99usd and free shipping. Got 4-each in 18 and 20mm. The brown ones are just to have another color available and the red and green to wear around Christmas time. They're not as good as the "real thing" but not too bad either. For 4usd for all 4 I can't complain. Will I buy more of these cheapies-probably not. But will definitely keep these. But they're about 1-2cm shorter than a NATO so if you have large wrists these may not work for you.
