It would be even better if it could scan more systems but upper models can with a premium being required in purchase price. The KW850 I purchased in the past worked well on everything it was claimed to work on and I had no issues with any defects. This scanner is large enough physically for persons with large hands to hold onto and operate. 100% happy with this tool. ### ⭐⭐⭐⭐⭐ BEST VALUE for the MONEY *by M***Y on December 12, 2019* This OBD Scanner is awesome. I have purchased several different types of scanners over the past few years, and can say while this one was a little more in price it's definitely by far the best scanner I have purchased yet. I like to keep a scanner close to me so I have chosen to purchase several of these to keep in my vehicles for my use and others as well so if I purchase another one in the best future it will be a repeat order. In other words I will go into my Amazon History of orders and hit but again on this particular unit. So do I recommend this for a purchase? Highly recommend if you find one 40 dollars cheaper to turn your head and just move forward with purchasing this one. It's definitely worth the money. ### ⭐⭐⭐⭐ No tiene mucha inforacion *by C***A on November 8, 2019* No es lo que esperaba --- ## 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.com.ar/products/139652289-konnwei-auto-obd2-scanner-professional-car-obd-ii-scanner-diagnostic](https://www.desertcart.com.ar/products/139652289-konnwei-auto-obd2-scanner-professional-car-obd-ii-scanner-diagnostic) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-18*
