Drew –
Worked perfect. No issues. Delivered as expected, plug and play. Confirmed by phone prior to purchase the model#, very helpful staff
Mark Phillips –
Perfect fit for the Hitachi/Metabo 15 ga angle nailer

I liked the fact that an alternative MPEM exists, but either my unit was bad, or there was a constant draw on the battery that would drain it eventually. Given the cost, sticking with used aftermarket would avoid fitment and the need to play with adjustable timing settings required for this unit.
