@ButterMackrel basically any J2534 compliant adapter will work. The problem with cheap ones like the one you advertised is that they might not work at all, can even damage your CEM the first time you plug them in, or will fail after some time as they don't have the correct internals/are build with low quality parts. The original Atmel chipset which can be found in the Super J2534/Mongoose Pro sold by D5T5 and it's partners costs much more than 40 Dollars. If an Mongoose adapter costs less than that it's 100% low quality. Most of those low price adapters are not even Mongoose clones. Instead they are crap like Vxdiag/Vxnano or Scanmatic SMII inside a mongoose shell.
