Wow! Nice work! Glad that ended up well for you. I personally would be scared shitless to try and tweak the coil. I'm sure I'd screw it up, or break it, or something. If this were my FF I'd just spend 10 bucks and send it to FF to fix, but again I am all but assured to mess this kind of thing up. It's actually surprising that such a small positional change would have such a dramatic effect, but I guess that explains the variations we are seeing reported from unit to unit...because I can see how easily the coil's position might be a teeny bit different in some units, despite quality control. And that could explain why every unit seems to have a bit of variance.
Which leads me to Day Five with my new Red FF. I have noted the following differences over my Silver FF:
- Battery cover fits more snugly. The silver's didn't come off by itself or anything but had a slight play in it, side to side, at times.
- Heat button is weird. I'd almost call it "mushy"...sometimes it's tricky to feel the detent position when you push it in. It never fails to work, but I'm a bit alert for issues with it. Hopefully it won't cause any operational problems. The button on the silver unit had a weird side-to-side play to it. Also weird, but different weird.
- Heat shuts off after 30 seconds of holding down the button. The silver shuts off at 45 seconds.
- Overall, a touch cooler, or should I say it cooks in a smoother, less heat-spikey fashion. ABV is almost always very even, almost never see any charred bits. Basically it's getting to the same temp and level of extraction, but it takes longer with the button to get there, particularly in the back half of the session. I have a feeling this one is calibrated the way FF intended, though the silver worked great...It just got hotter faster and so technique differences are required between the two FFs.
Be interesting to see what I get back from FF...if they replace my silver one, the new one may be more like the Red than the old Silver. And if they tweak/repair the Silver, that could affect temp profile also (in fact it absolutely will). Life is never boring in FF Land.
Bottom line: Red FF is gorgeous, works great, extracts as well but more smoothly and evenly, and is noticeably different than the Silver.
