SHOTS SHOTS SHOTS!
You can't live with 'em, you can't live without awkwardly spilling a two-liter of Code Red Mountain Dew all over yourself after every one. Messy, painful, but a necessary party evil. So for those of us who wouldn't mind if shots went down a little smoother, the Snapshotr double-barreled glass is here to alleviate that agonizing post-shot after-bite.
(Also it needs to be said: if you take shots so frequently that you're in dire need of custom barware to make them more tolerable, you may need to examine your priorities.)
