I got my 'Cook's Essentials' Pressure Smoker today. It does what they say it does. I 'smoked' a 2.5lb beef spoon roast in 50 minutes and it was tasty, tender and smoky tasting. It was easy to clean up and easy to operate.
I dipped my feet in a little further afterwards, trying to cold smoke a chunk of fresh mozzarella. It didn't work so well, but I believe there was some user error on my part. There was plenty of smoke, and I think it would have turned out nicely had I left it in longer and not opened the cover to 'see what was up'.
All in all, it's a pretty cool toy for $140. I wouldn't throw down $200+ for it, but if it keeps turning out tasty meat like it did today I could really get used to using it.
Caveat: I spent a summer a couple of years ago slow smoking just about everything I could get my hands on. It's NOTHING like 'real' smoking. It's a clever tool that gives you SOME of the benefits of smoking without a lot of the hassle.
