Don't neglec outsourcing.
The amount of rebranding would make it difficult to know what you're actually buying.
A you tube clip I looked at a few weeks ago had a guy checking out a few genuine and alternate replacements.
Three were Toyota OEM spares, in identical boxes and part numbers. On cutting them open they were all inferior to some of the third party ones, with cheap valving and weak elements. All three were totally different inside.
The ryco I cut open a couple of years ago looked a smidge more robust than the mitsi part and the sakura, Nippon max , etclooked oOK also.
Bottom line, I don't see spending three times the amount offers any better value.
