Right off the bat, being a gamer, I LOVE the theme of Level Up! The names and artwork on the bottles are awesome. Not to mention, the frosted glass bottles are gorgeous.
I've only ordered from Level Up twice, and I haven't even received the second order yet (just placed it yesterday). After placing the second order, I emailed Level Up to give them a heads-up that my bottles were a little leaky. No biggie, just wanted to let them know. Colby is amazing - I'm being sent a replacement bottle of the juice I ordered. Totally not necessary, but EXTREMELY nice! Best customer service I've ever received from any company.
The two juices I received (one ordered, one sample thrown in) were AMAZING. Easily the best juices I've ever vaped. You can tell the quality is there, that each flavor was developed with care. And to top it off, their prices are very fair - 120mL for around $30 is something I can absolutely justify spending for this kind of quality.
After being repeatedly disappointed by ordering from various online vendors, I'm so happy I took a chance with Level Up. If you haven't tried any of their juices yet, I highly recommend doing so.
Edit: It's been three years since my initial review of Level Up Vapor. The prices have since gone down ($19.99/120mL), and the quality and customer service is still there. Since my first review, I have continued to order from Level Up and Level Up only. It's a fantastic business with an even better owner and fantastic juice. I absolutely cannot recommend Level Up enough.
