Same. Customer service won't reply. Jason's on the ball. Or there really is no customer service and it's just Jason, but he's helped me so far and I appreciate his help, so.....I didn't just say that.
I'm just making a point. Their people need to reply to the emails. It's not that hard. It's a part of doing business. If they refuse to reply, then don't offer that as a contact route on the website.
I have received defective parts once and they replaced them quickly. I've also learned through use on how to better use the device and extend the life of parts, so give it a chance. It's my favorite ecig yet.
The person that flat out got a broken order (nothing worked), that sucks and I think they just need to send you a new replacement kit. Bad piece of the batch I guess.
I'll say from experience that while the Blu carts work awesomely with the device, I agree that the # of puffs is limited but refilling the carts is reasonable. I've tried Johnson Creek and Totally Wicked. The TC juice basically is too thick or something for the device and I had to clean the atty daily, but JC will last a week between cleanings with no issue and handles the Blu well.
If you notice degraded performance with the Blu atty after a little bit of time, try unscrewing the battery from the atomizer (with the cart still attached to the atomizer) and blow reasonably hard through the cart (pushing excess liquid out of the atty). The atty floods sometimes and this will make it work like new almost instantly.
You might want to cover the atomizer end with a tissue to soak up what you're blowing out. Don't overfill your carts and you'll last longer between needing to "de-flood" the atomizer.
Also, I've found that taking out their filler and replacing it with a custom-cut length of polyfill works amazingly for this device. It allows the juice to reach the atomizer wick much easier, allowing for prolonged use between cart refills.
I hope this helps Blu buyers that are just starting out. I've become sort of an afficionado with Blu
