Does anyone have one? Thoughts? I have a cheap-o metal bullet that I rarely use, and when I do it’s to portion out snuff either box car or back of the hand. Would this be a better alternative?

I have two I find it works great for some snuff but is a pain in the ass for others. Your money is better spent on a Patrick Collins Tripletek box.

I have a toque flask attached to my keys so I can’t leave home without snuff. It holds plenty and perfect for boxcar or back of hand. http://www.toquesnuff.com/ click accessories .You can buy all three 

@normfeth - I have the SS one; it’s alright, very robust (if a little heavy) and isn’t going to break any lifetime soon. The cap and base are removable to facilitate easy cleaning and they hold a good volume of snuff. Moist snuffs stick slightly, and dry snuffs can run through the mouth of the flask a little quickly. With some practice its good for a boxcar or the olde off the back of the hand number. These are nice items but also a little on the pricy side; there’s a lot of wisdom in @basement_shaman 's comments above - In summary I guess better than a bullet, but not as good a box!  

I don’t really like it. Too small to be really useful, probably only holds a gram or so. Also, the opening at the top is too small to be really useful, so I found I needed to unscrew the base and use a spoon. I do find I use it sometimes when I want to just warm up a gram of SWS snuffs, which I usually store in the fridge. I’d recommend the Toque flask or, for dry snuffs, the Patrick Collins’ box, which is my very favourite snuff box.
