DON'T BUY IT! *by D***N on Reviewed in the United States on October 5, 2019* It works well enough, but the battery is dead EVERY time I try to use it. At first, I thought that it had perhaps rested on the button, turning it on while I wasn't using it. Finally I tried storing it in a little hard plastic box. Still, the battery goes dead in less than two weeks. Pay a little more for a better tire gauge, and save big on batteries! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/66622324-smartwhiz-mini-keychain-lcd-digital-car-tyre-tire-wheel-air](https://www.desertcart.hr/products/66622324-smartwhiz-mini-keychain-lcd-digital-car-tyre-tire-wheel-air) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-19*
