This thing worked great and appears to be well made. I basically just wanted a break out box to make testing easier without having to probe the actual DLC Connector, but the LEDs are really helpful, immediately showing power and ground as well as communication. It's nice being able to have a scan tool attached while doing testing. Not a tool I will use often, which is why I hadn't bought one before, but for the price of this one, it was well worth it. Came really fast which is another reason I chose this one over others. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars The item works great thank you *by J*** on Reviewed in the United States on October 22, 2019* The item works great thank you ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Works great *by A***R on Reviewed in the United States on December 24, 2018* Showed up looks just like the images.... --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/75311593-gsll-car-can-test-box-fault-diagnosis-scan-tool-obdii](https://www.desertcart.com.ar/products/75311593-gsll-car-can-test-box-fault-diagnosis-scan-tool-obdii) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-15*
