Good value on bundle

I was looking for a good deal on test kits and found their Complete Drug Test Kit Bundle. It was a much better price than buying everything separately. I also signed up for their newsletter and got a 10% off code, which made it even more worth it. The shipping was free since my order was over $100. It felt like a smart purchase overall, especially with the extra savings.

Decent kit, slow support

I bought the Cocaine Purity Test Kit and some Protective Gloves. The kit itself worked fine, and the instructions were clear. However, I had a question about storing the reagents, and it took almost two full days to get a response from customer service. While the product quality was good, the slow support was a minor inconvenience, particularly for something with a shelf life.

Smooth order, good quality kit

I ordered the Complete Drug Test Kit Bundle last week. The ordering process on the website was straightforward, and I received an email confirmation instantly. Shipping took 5 days to reach Denver, which was within the estimated timeframe. The packaging was discreet, as promised, and everything inside was well-protected. I used the MDMA Test Kit and the Fentanyl Test Strips over the weekend, and they worked as expected, providing clear color changes and results. The instruction manual included was very helpful. I had a quick question about storage, and their customer support responded to my email within a few hours, which was impressive. Definitely a reliable service.

Got my stuff, all good

Needed some Fentanyl Test Strips so I ordered them. They got here pretty quick, like in four days. The packaging was discreet, which was nice. Everything looked good when I opened it up. No complaints.

Reliable as always

This was my third time ordering from Test Kit Plus, and they're consistent. I got Replacement Reagent Bottles for my Marquis and Mecke kits this time. Just like my previous orders for the Ketamine Test Kit and the Cannabis Potency Test Kit, everything arrived quickly and was well-packaged. It's good to know I can always count on them for fresh reagents when I need them. They haven't let me down yet.

Hey, wondering how long shipping usually takes for these kits? I'm in New York and need one kinda quick.

Yeah it's usually pretty decent. Not amazon prime fast but quick enough, I think mine took about a week to California when I ordered during a busy time of year.

Is Test Kit Plus the real deal or should I go with DanceSafe? Heard some mixed things, wanna make sure I'm getting accurate stuff.

They're legit. I've used their kits for years, always matched up with lab results when I've bothered to double check.

Honestly, Test Kit Plus, DanceSafe, Bunk Police... they all use pretty similar reagents. I've found TKS prices a little better sometimes, especially on bundles. Accuracy wise, they're both solid.
