Ordered the manual tensioner to replace stock. Stock cap was dented. It's definitely a quality item and easy to install. Just remove old tensioner parts (bolt,washer and spring). Inserted, tensioner, set, and lockup nut. Very straightforward.
Only thing is there doesn't seem to be any specs on how tight to set the tensioner. I recall only one video (i think by huntertuned) that actually states how much to tighten. So recommendations would be nice.
As for customer service and shipping. Always great at DHM.
