Same code l, two different vehicles. Highly unlikely that both have the same failure. Observation of those lights does not confirm problem. ### 1/5 — Useless *2026-02-02, version 1.3.9* Even basic coding is either impossible or needlessly frustrating. ### 1/5 — Poor *2026-01-26, version 1.3.9* Can’t even code a battery in on a qashquia with it even know they state you can when buying … save your money and buy something better ### 1/5 — Audi A8 *2026-01-11, version 1.3.8* Very disappointing experience. I bought this to reset the AC, but it required an extra $32 payment. It couldn’t fully clear all codes, and overall it was a waste of money. I had another device before that worked great. I sold this one on eBay for £30 because it was just wasting my time. ### 1/5 — Extremely complicated, not user-friendly *2026-01-09, version 1.3.8* This device is very difficult to figure out most code readers plug them in turn the key to the on position it throws out the codes. This one is not like that at all. ### 1/5 — Slow as molasses *2026-01-02, version 1.3.7* No instructions, too slow ### 2/5 — Requires network even after first connect *2025-11-30, version 1.3.6* Got an error code in the wilderness. Could not scan till we went back to coverage area. This was not first time connection to the solo scan. Had used it many times before ### 1/5 — Reset options aren’t free *2025-11-23, version 1.3.6* It’s not free subscriptions yes maybe to update the core is free but if you are trying to reset tmps, brakes, airbags or any other trouble light or any code outside of regular parameters of an OBD two reader they want $19.99 for each one options. So $19.99 for tmps reset+$19.99 for brake light reset+ $19.99 for airbag etc. I think it was sneaky of them to make it so when you look at the app, it doesn’t say add-ons or anything like that. They added it through a different section where you have to redeem a code so it doesn’t show up like you don’t have to pay additional fees for anything buyer beware. I had mine for about 10 minutes and I’m process of sending it back to Amazon ### 1/5 — Ford galaxy *2025-10-22, version 1.3.6* Not working for code readers and repair ## Most critical reviews (10 lowest-rated) ### 1/5 — Not good for Velar *2026-08-02, version 1.4.1* Rubbish - does scans but won’t clear any warning codes detected ### 1/5 — Latest IOS Doesn’t Work *2026-07-12, version 1.4.1* App does not work on latest IOS update.
