I'll start this off by saying I absolutely love my Avocado 24. It's quickly become one of my favorite flavor tanks. My only complaint after a few months of use is one that many people have experienced. It has to do with the 510 peek insulator. It is really tiny and easily lost. In fact just google Avocado peek insulator and you'll see pages of people that have lost this stupid little piece and can't find a replacement. It's bad enough that they don't include a spare of such a tiny part that easily gets lost but to not have spare parts readily available for purchase is just inexcusable. I posed the same exact question to Geekvape and what I got was a snarky response from some ass hat named Calvin. Dear Jack You are very welcome we love to help our loyal customers. I wish there was a world where we could lose stuff and get it replaced for free but thats not the way our business works. We appreciate the feedback, have a great day! Thank you for choosing GeekVape Calvin Pruett Customer Service Agent [email protected] This fool is a customer service agent? What a condescending asshole. I guess Geekvape goes on the same list as Sigelei and Smok. SMFH! for the record I never asked for a free replacement just for a place that actually had them in stock. I did inquire as to why its not included as a spare part.
