Martins Industries Flatematic Handheld Automatic Tire Inflator - up to 174 PSI, Inflate and Deflate Automatically, Rechargeable Lithium-ion Battery - Loud Signal and Stop When Set Pressure is Reach

Works perfectly. Very happy with the tire inflator. Makes airing up class 8 fleet not as annoying.

The only thing I would like to change is that the head is quite large and it’s not fit for tight places

It works well for truck tires and farm equipment tires just set it and keep working on other things

Best inflator I used for semi and work perfect!

I liked it it was working good but there is one problem after a few times it started not to work and I can’t get hold of technical support. That’s why I gave one star on overall and five star on the three items easy to use easy to read, etc.

I have 6 Mtn bikes that are tubeless quick connections no problems with air/ deflating automatically.

I loved this unit. It was very accurate and convenient. Well worth the money if it kept working. After about 3 years of occasional use (mainly to check trailer tires for trips, and air up after off roading, not a commercial environment by any means), the battery would not hold a charge, would only work while plugged in.Reached out and martins advised that they do have a replacement battery to purchase, or to go on amazon to get one. I did but that did not solve the issue, i checked both batteries and they had good voltage.It has now stopped working even plugged in.I was well aware that it would be out of warranty but wanted to send it in for service (and fully expecting to pay for the repairs), and was told they do not service these and to "discard this inflator and purchase a new one".I find this ridiculous for a $300 tool.I realize that electronics go bad, but to not service or help out on diagnosis of the issue is not good customer service.Customer service was quick to respond (just not with anything helpful for my situation),Its a shame too because this tool was fantastic when it worked.Just be ready to shell out $250 -$300 every 3 years or so if you want another one.

works great and easy to use
