Bosch OM 036 vs. BD28 (don't sweat, its an new old stock from way before the "shortage").
Bosch has no crimping and has less holes. Its also wider by a bit vs. the BD28
Bosch has bottom canister plastic shrink wrap. Both have fluted tops. BD28 slightly narrower but taller.
Bosch is made in Korea (If I'm not mistaken).
The Bosch is probably a great replacement to the VIC C306 and if I'm not mistaken its also cheaper at Php 350 a pop. Solidly built and feels heavier than the BD28. I plan to put this in the L300 delivery with 3xx,xxx kms and replace that Vic C306.
