There is a screen built in to the heating chamber; so you don't need to worry about that. Herb is not going to come in contact with the heating element, and the capsules fit like a well made glove. I double checked and my timer lasts for 8 minutes as well, which I like alot better than the 6 minute timer it would have had originally. Although I feel I have to mention, I did just combust with mine. I also must mention it was my own damn fault; but it is possible. I was bonging with a capsule pretty much brim loaded with kief and on MAX and I guess I hit it a few too many times. I think the MAX setting is good as a quick jumper to get the last out of your herb but I don't think it's meant for normal operation. I'll be keeping it on 9 from now on, the clouds are big enough on that one anyway haha. Anyway kushcabbage; congrats and I'm sure you will be getting your soon. Which side of the border are you on?
