Armory Den = HELL YEA! 🙂 Finally a company who doesn't rip people off. I searched forever for a trap kit that matches industry design and option. Ran into tons of scam sites until now. I bought the 304 Steel Adaptive Trap (10" inch) and that was on a Friday. That same night or the next day they already had USPS label from Florida and it shipped out that same day! Armory Den is the best site out of all the knock off scams or just plain fraudulent sites claiming to sell traps. Everything from their shipping to the transparency of sells via Stripe payment, keeps reputation in the front seat. Thank you whoever runs Armory Den. You are doing so many people favors. Your prices are cheapest along with design and materials offered. Its China that makes knock offs and Armory Den DONT PRODUCE OR SELL THAT GARBAGE. (P.S. stay away from Solvent Traps Direct).

Amazing! Absolutely thrilled with the level of customer service. Anytime I had a question they respond very quickly and always answer my questions completely. I love their packaging. While it may be somewhat difficult to get to their products through all the packaging, I really appreciate that they take the time to properly wrap their products. I feel like this attention to detail would protect my order if the delivery person were to leave it where it could get rained on or left in the weather. The packaging is amazing, and I will continue to return as a customer.

Outstanding on all fronts Great company! I am 110% satisfied with my experience. The ordering process was easy and secure. The package arrived 3 days early by USPS. The product was extremely well-packaged: outer bubble envelope, inner bubble wrap, a box, and the individual pieces were separated and secured within holes in foam material. The trap itself is very well constructed as advertised. I’m glad I paid the extra $$ for a high quality product rather than risk with a random internet company just out for sales. Also customer service responds within hours and is extremely responsive—they have actual humans interacting with you! Will use again. Thx!

Solid from website to my hand, top shelf As I shopped for the product, I kept returning to the Den website. Descriptions are clear, lots of good information, very good value. Ordering is simple, terms are straightforward. I had special shipping instructions, followed perfectly. Secure packaging. The trap is well machined, fits tight, and is nicely finished. The hand-feel has heft and is of quality. Extra care at every step. Thanks.

They did the right thing! Let me just start with Thank you Armory Den! What exceptional customer service! Their response time to emails, is faster response time then the police department has where I live for 911 calls lol j/k. Seriously, they answered me on Sunday, morning and afternoon. No company does that! Also, I asked about a part I thought came with my order. I was ready to pay for it, nope, they sent them to me for free, and shipped on a Sunday! No one does that! I’m a customer for life! I even canceled an order I had with another company, just so I can buy from ARMORY DEN! My business motto is “always do the right thing l, no matter what” they obviously follow it also!

This company is the real deal I was a little skeptical about ordering honestly. I hadn't heard much about armory den and could only find good reviews lol. But I took a chance and put through an order. Everything arrived as described and is awesome. Be aware that you may receive multiple shipments based on what you order. These guys respond fast and from what i have seen, produce quality products. They have my future business. I've put up similar reviews and given a recommendation on their FB page.
