They look well built. Cant wait to get get mine.Another happy customer here- I received the vaporizer from Joerg today just in time for my fall treatment start. It worked fine right out of the box (I did a couple of dry runs and one with water just to clean any residue) and I treated 10 hives in a fraction of time it would have taken me when using the wand. Also this allowed me to treat the nucs that don't have entrance hole big enough for wand head. The best part is that I can do it from the back of the hives without having to stand in the fly path of the angry bees that find the entrance closed. Silicone plugs are very easy to insert and remove without any tools, temperature control is spot on. Plus it is made in Canada, happy to support local businesses! Thank you, Joerg!
