The vaporizer itself is wonderful. I've had a few handhelds and desktops over the years and the Rogue is by far one of my favorites! But, the dosing capsules leave a lot to be desired. One of the main reasons that I purchased the Rogue was the fact that you could use dosing capsules to help keep things cleaner and more convenient. But after their first use, the lids to the capsules seem to get welded to the body and need a knife to be pried apart. I wish there was a better design with the dosing capsules, but the Rogue itself is amazing!!
