It's pretty great. Great for using the Ditanium for those mid-day, one-hitter type tokes. It is a little finicky, depending on the position of your Ditanium.
Mine is on a neck height shelf, and this pipe works perfectly at that height. When it was below me on a table, it was an awkward angle. You kinda have to perch over it and tilt your chin into your neck. It would still be a 5-star with that issue but, I put it down to four stars because there is no easy way to remove the screen. You're forced to try and lever it up, whereas, with the conventional bowl/handle, you can push them up from underneath with a stiff paperclip or a metal pin.
This cleaning issue, for me, leaves it more like a smart curiosity, than a daily use piece. I also can't even think of a solution to the problem, so it's hard to slight it for it. If you usually pull your screens up, from the top, rather than push from the bottom, it won't matter to you at all.
In the "just useful info" category, the smaller bowl brings the flower much closer to the side mouth of the e-nail, Meaning that your temperature settings are a little different for this piece than the standard one. It runs hotter. It also makes it good at vaping kief/hash on top of some flowers. A little hash nub stuffed into the top/center of the flower puck works wonders with this device.
All-in-all, it's a beautiful little piece and was a good value. It's earned a nice little display place in my cabinet, and it's been nice to pull it out when a friend wants to try a hoot of a specific strain in my collection. Also, it's the most inexpensive I've seen to make sure if you break your regular whip, that you can still use your Ditanium.
