Looks like a generic China unit as sold by companies like RM Stator and Electrosport. For my money I'd get a Ricks. I also recommend a SH-775 R/R, it will help protect the stator from shunted current causing it to cook. Stators like linked that make "20% more power" also cause 20% more current to be shunted back into the stator, thus cooking it even faster, unless you are using the power for something like heated gear.
