## What reviewers say

**TOPDON TopScan** — Only one whitelisted tester, Tom's Guide, hands-on reviewed the exact Topdon TopScan, and it earned Editor's Choice. The reviewer praised broad automotive diagnostics, live data and rare performance metrics like 0-to-60 mph times plus horsepower/torque and volumetric-efficiency estimates, but flagged a big, heavy transmitter and a subscription that kicks in after the first year. The observed Bluetooth range was about 25 feet. Retailer, forum and non-whitelisted auto-blog reviews were excluded. (1 sourced review.)
