I'd taken the plunge on the UFO IH, despite my better judgement given how they've acted on social media, among other potential red flags. TBH, the price I found was hard to resist (although I wish I had).
While I was happy with a couple aspects of it - such as the form factor and the customizable heating profiles, it turned out to be really glitchy and unreliable. Mine wouldn't charge correctly and would randomly shut down. It also came with shoddy QC/fit and finish. I wouldn't recommend this company or device to anyone based on my experience, as well as other perceived red flags on their business practices.
In contrast, I have nothing but good things to say on Fluxer (if he ever gets back in business), Pipes (Portside, Hotshot, etc.), and the Ispire Wand. For folks potentially on the fence about the Wand as a dedicated IH, if you think you'll ever need a concentrate option as well - the wand does a great job there too!
