I appreciate the great people I’ve met through this site, and am heartened by the many emails I receive regarding our designs/products – here are just a few.

Hey got everything in. Made the blowbox and it blows cold! Awesome little project. Great for the night shift where I’m stationed in a little shed with no a/c. Unlimited ice at work is a plus. Thanks for everything!

Took me about an hour but super easy with the instructions, thank you! Have small mods left but everything works perfectly!

I would say this project was a success! People are really amazed with this cooler! Everyone asks me “How much did it cost?”. I haven’t tallied up the numbers yet, so I don’t really have an answer. The best route to go, IMO, is to buy the kits from you to simplify things. At first, I looked up the parts and discovered is just as economical (as well as quicker and easier) to purchase the kit from you.
Thanks again for all your help! You’ve been great! 😊

I wanted to send my dearest thanks to you. The blowbox you built for me has been such a blessing. It works so well and I’m so grateful you took on my order. I was even able to bring it to the beach on a 90F+ day and it kept me cool for hours.
Thank you and I hope to do business with you again for another Frankencooler down the road. Stay safe, stay healthy, and stay cool.

Just want to say thank you! Cooler output is around 36 degrees cooler. Used it in my mail truck yesterday. I have to get out and load mail at each stop but it made it bearable for me yesterday being out all day in 118 degree heat. Every time I jumped in the truck to head to the next stop I was able to cool off with cold air blowing right at my face. Made a huge difference and couldn’t be happier. I have to throw a separate cooler Behind my seat for fluids which is not a big deal. Since it was not running constantly all day it only went through 2- 10 pound blocks of ice. Used it from 10:30am when I left the post office to 5pm when I returned. Maybe eventually I can upgrade to a blow box. It would be fun to build one.
