I have 1 it is the best invention ever lol. No, I use mine all the time works perfectly every time with no smell. Now when you open you can smell it but that's unavoidable I just open it in my garage. Some say it's to much money, and I agree $180.00 is a good amount. But it pays for its self over time. Some people are in legal states and dont have to cover smell so they can just do it in their oven. But I'm not legal yet so best way to cover smell is not to have any, which this does. Also if you have ever decarbed and it's not strong or didnt work? Now you wasted that bud, well I wasted several oz's way more then 180.00 worth. My case sometimes it worked sometimes it didnt and now house smells like bud. Ever since I got my lift perfect decarb, better than I ever did no smell. Plus I decarb rosin in silicone containers no problem. Just put in place lid on and hit button. Done 2hrs later ready to got. You can also infuse oil/butter after you decarb in it with no smell. I love mine would have paid more for it than I did lol. It's up to you, is perfect decarb everytime with no effort or smell and also infuse with it worth $180.00 to you? The only people that tell you not to get 1 are people who haven't used 1. Anyone that has used 1 will tell how great they are. I have no affiliation with ardent just a happy customer.
