Leaky pods, broken sensor.
Bought a Sonder U as my mate had recommended it as a great replacement for getting a similar vape style to disposable ones, which always seemed much nicer than any refillable vapes I had. The Sonder U was pretty good but after 6 months it has started to give up the ghost. Likely due to woefully leaky pods, the suction sensor for starting the vape is now intermittent at best, and when it does work it continues burning even after suction has stopped. This is likely due to leaky pods getting fluid on the sensor. I'd happily try to fix it myself but it's a sealed unit that cannot be opened for inspection without breaking it permanently. So I'm stumped now with a poor quality product. It might be a silly analogy but all I can think is, if society was able to engineer airtight submarines and space shuttles almost a century ago, it's frankly embarrassing that a company in the 2020s cannot create a rudimentary product that is safe from leaks or sensor damage. Tacky, low quality product.
