I just received the product and I must say I’m very pleased with it. The rechargeable one is better than I expected. It’s a nicer size and texture than the disposable ones and the USB charger is super handy. The blue light at the end is very cool – though if I could change only one thing, I’d rather have it be a more matte lighting effect (the glass crystal doesn’t do it for me). I look forward to buying more flavour refills in the future!
