Some delays, but 5/5 quality! Should cost more. I have bought or otherwise owned kits from most major vendors and a few small ones too, and none of them made me "excited" to own a jar of chemical reagents before this order came. I only have had the kit for one week, but over the weekend was able to verify that no reagents arrived expired, the volume is as advertised, and everything tested reacts the same as my Bunk Police and DanceSafe reagents did. Service was accommodating. There was a somewhat long delay, but they ultimately came through for me. My order was part of their opening sale and the reasons they gave for the delays made sense as a company just starting out. They upgraded me to overnight shipping and made sure I had the kit before the weekend when I said I had a show. They tried to offer more to make up for the delay but honestly at the current price, I feel bad that I took them up on just overnight shipping because I don't see how they would be turning a profit at all off this order. The guy who helped me was really courteous and helpful the whole time. The only other thing I would say is that if you need the stuff fast then make sure ahead of time that they can honor the shipping guarantees because it was clear they were struggling to keep up with demand a little bit. Great transparent company, hope to see them grow and maybe raise their prices a little to avoid delays and stay in business... :) 5/5 overall, keep it up!
