TST CAP System with 2 to 12 Sensors

Been testing this on a trailer with a known leak in one tire and it detects when it reaches below my setting of 45 PSI. I have a Longacre racing tire gauge which is very accurate. The readings from TST are spot on between 25 PSI and 60 PSI. I did not test above 60 PSI. Below 25 PSI it can be off by about 1 PSI. Great product and feel much safer now after going through the experience of a flat.

I ordered this product back in May and ended up getting ordering the wrong type of sensors for my RV. No problem. Contacted Evan who had to be the greatest customer service representative I have ever worked with. She had the new sensors out to me and was just a pleasure to work with. The TST product was easy to set up and has been working great. I was so impressed with the company I then purchased Viair 400 compressor from them. Just an outstanding company.

Like ordering from TechnoRv as the shipping is fast and they keep you informed all the way from time of order until delivery. I know with this "thing" going on now that they cannot control it but still received when promised. I have ordered other products from Techno Rv and have had the same great experience no issues. Like the fact that when you order a product they follow up with instructions on how to use it so you can get an idea of how it works and that you are doing it correctly. So far the TPMS system is working great found out that my tire gauge is spot on so that is a good thing. Like the ease of programming and the color monitor is a plus.

Just installed the TST on my motorhome and it set up in a breeze. Very happy with the display.

I wanted to commend Evan for both her knowledge and kindness in several calls and videos in getting the cap sensors working properly and rounding out such a great system...It makes such a difference when a product is backed up by folks that care and really seem to enjoy helping their customers...That is hard to find these days it seems but with Evan and Technorv it works so well. Thanks to each of you and best wishes Steve Freeman and family

I have put thousands of miles on my TT with the STS system on it and it does the job quite well. I like the color monitor, easier to see even with sunglasses on. Also thank you guys for the excellent support when I needed it. I am a Techno RV fan !!

We live full time in our 8 1/2 ton 5th Wheel with 4 dogs and 4 cats. With my entire home and family on-board, safety is a big issue and a TPMS was a must.

Our Ford truck has an existing integrated TPMS but the kit for integrating the 5th Wheel's tires was $600 plus installation.

While I did not want yet another monitor on the truck's dash to make it look like a "star wars" cockpit, installing a top-rated system at half the cost of an OEM option was compelling. As it turns out, the small but easily readable color monitor of the TST system fit neatly in a center-console cubby, with the friction mount holding it at just the right angle to see it. You don't need to stare at your tire monitor while driving but if we hear an alarm sound it's easy for either one of us to glance down to see what's the matter.

Installation and set-up was easy and intuitive with the help of TechnoRV's "Learning Series" videos that come with their products. Their videos are well produced, making them easier to watch than many YouTube "instructional videos" made by some joker with a selfie stick.

Our first trip with the system was our mandatory evacuation from Coastal GA in the path of Hurricane Dorian. We were a bit frazzled and stressed with all the unknowns bearing down on us, but it was comforting to have the TST system in place and monitoring the safety of our home on the road. While we luckily did not have any tire troubles, the system worked as promised and made it easy for us to keep informed.

Our next purchase will be a dedicated RV GPS system and we will favorably consider the offerings of TechnoRV based on the service and support we have received thus far from Eric and Tammy's crew. I like their business model and appreciate their firsthand experience.

I went with four of the caps and two pass thru sensors. The pass thru sensors I used on my inside dualies. I eliminated the braided valve extenders, they always seemed a little sketchy to me. With the TPMS I do not have to go manually check tire pressure before each trip. Woohooo!

I really like the quality of the TST 507 kit. Color screen. Easy programming. My only complaint is I wish it charged off of a USB-C cable (it uses Micro USB)...minor gripe. It comes with a suction cup mount and the grey, grippy stand shown in this photo. I probably would not use the suction cup mount except that the grey stand is great for a smartphone.
