Has anyone experienced this:
I had a 5 minute session yesterday, at 380 degrees. Full oven. Got done and thought I turned the unit off. Set it down. 5 minutes later, I notice that I smell a burning smell. Pick up the unit and it is burning hot, very uncomfortable to hold. The control button and up/down arrows were illuminated in a white/pale light. None of the buttons would work to do anything. I couldn’t turn it off and it felt like it was getting hotter. I had to take the battery out to get it to turn off.
Once the unit cooled, I checked the oven. All the herb had turned to black dust. It was fully incinerated. Unlike anything I’ve ever seen In a vape. I cleaned the unit but it still stinks. Not sure that smell will ever leave. Which is a deal killer if so. I really liked this vape, for the flavor. So much so, that I ordered a backup last week. Now, I just don’t know......
I currently own 2 IQ2's each with their own fair share of problems. What you just described is what is wrong with my first one. It rarely happens but when it does, it enters a runaway heating mode cooking the entire bowl and requiring extreme cleaning. This has happened 3 times in the past 6 months.
I caught it last time when I heard a bubbling sound. It essentially boils the entire bowl in seconds and if left to run, it just solidifies everything onto the wall of the bowl to be scraped off for at least an hour. The only way to turn off the unit in this state is to remove the battery.
So in total, that IQ2 also has the following 3 issues:
1. Shows battery is empty when the battery state of charge (SOC) is below 90%. Have to plug in the usb cable to add enough power to allow the unit to run for at least 10 minutes before shutting off when the battery reaches 90% SOC. I bought $50 worth of brand new 18650's to make sure it wasn't a problem with the batteries I was using, but after testing 6 new batteries fully charged, the same problem exists.
2. Unit randomly lights up entire led display for a couple seconds and flashes 3 times before shutting off
3. Unit rarely enters a runaway heating mode cooking the entire bowl and requiring extreme cleaning. This has happened 3 times in the past 6 months. When it happens, I have to remove the battery to get it to turn off.
** Note - The above IQ2 was warrantied last year due to not powering on anymore (same issue my second IQ2 now has). I actually purchased my second IQ2 below when I sent my first one to Davinci for repair so that I would have a working unit.
Unfortunately, my second IQ2 doesn't even turn on so I'm currently warrantying that one now so that when I get that back, I can send off the one with the problems above.
My second IQ2 has the following 3 issues:
1. Unit won't turn on. When inserting a new battery, it shows the battery level (full), but the power button no longer works. This happened to my older IQ2 last year.
2. The battery door has been difficult to use since day one. The latch mechanism doesn't want to release most of the time even when the latch is pulled back all the way. When putting a battery in, it doesn't want to close all the time and it takes up to 5 tries to keep the door closed. When no battery is in, the latch doesn't want to open easily.
3. Dosage Calculation / Draw Detection never worked from day one. When inhaling, the display is supposed to show a counter as you inhale and light up the power and up/down buttons. This never worked with this unit.
It's really unfortunate as I need a working product hence owning 2. I'm currently researching other brands/products and will likely be settling with the Storz & Bickel Mighty as I can no longer rely on the IQ2.
