Canadian here reporting. Just received the caps today. All 6 open for me, but I have tiny girly hands so I guess that helps. I use the tool to help with those that were a bit stuck (2) but I didn't force them to open. They were soaked in alcohol, washed, and dried before I used them.
This is after use, I removed the microdosing disc and stored it away. For some reason I feel like my flower ran out faster than it usually does. I usually pack the bowl prior to having the caps to full with the first minute on 180, then turning it up to 195, then up again to 210 on the last minute for a total of 5 minutes per session. With the caps it's done in about 3 minutes which is still fine, I just have to learn how to find a groove again.
Caps after removing from the oven and removing the roasted flower, I kinda hate that it still has debris and I can't seem to remove them. I am not sure yet how fast the caps cool down. But you do need to use the tool to fish them out. So far from experience (1 cap used lol about to be 2 after writing this), took less than 30 seconds from fishing it out to trying to touch them to see if I can remove ABV.
I am not entirely sure I feel about these yet, I just got a new batch to smoke so I will probably check back in a few weeks. I thought I will stick with just the caps now, but honestly I am not sure yet. I do mostly of my smoking from the AVLP on session mode and I really don't find it that hard to clean (I have learned how to ignore the state of the actual bowl and gave up on cleaning it but I still wipe it when I clean the device from time to time [1x a week or 2x, depends I guess]). Not sure if I'm happy with a coarse grind on a BGC to use on the AVLP with the caps, I will test that out as well.
