My Invader Mini arrived yesterday (had been using a vw mod until now).
As others have said, temperature control makes all the difference. This is now by far the best bho cart I have ever used in terms of flavor, convenience and, most importantly, cleaning! I can get the ceramic donut back to white every time before loading new material, so essentially have a new cart each time. This is a feature I have been looking for in a wax cart for ages, so I am delighted.
The hits with temp control set to 220° (as Matt recommends) are outstanding! My only very very small gripe is that the air holes are set a bit too low inside the chamber. If they were 2mm higher, I could load more at once. This is the first portable combo I am actually recommending to friends and fellow patients without reservation (w9 stuff was not bad, but way too fiddly and tough to keep clean). There have really been some big advances in this market over the last year or two. Let's hope it continues!
