Bests & Worsts Reviews from Amazon

If bought from Foseal, these work great. There are quite a few manufacturers selling apparently the same Item, but don't be fooled. I work in the automotive industry and have the opportunity to try this on a wide selection of vehicles both models/years/make. I have had to send back multiple other manufacturers product because they would link to my phone and that is it. I found the electronics to be different. I have dissected a few and came to one conclusion. The scan tools with a SOLDERED on bluetooth board all seem to have the same PC board. These ones function. The ones that dont work have similar internals, but the one difference is the bluetooth board is INTEGRATED. These have an extremely high DOA rate. I searched through seller pictures and found one (sold by and branded " foseal") that I could see the bluetooth board soldered on. I purchased 2. Both function perfect even with my scan program set to fastest communication. I have tried these on a 2003 Hyundai Elantra, a 2005 Toyota Tundra, a 2000 BMW 328i, a 1999 Mazda Protege', a 2005 Chevrolet Suburban, a 2009 Cadillac DTS, a 1998 Honda Civic and a 2010 Toyota Tundra. All had perfect communication and read the VIN# on all vehicles. This was a wide enough range of vehicles to deem this scan tool functional on all vehicles. Thanks for a great product and please click helpful if this was informative!
