Bando.
Hands down best quaity for bulk standard size belts. Very precise width across its full length, dayco and gates are nowhere near the quality.
These bando belts seem to have tolerances of around +-.1mm (.2 total)
Others vary from gates with +-.3mm (.6 total) or dayco which has the worst at around +-.5mm (1mm total wtf?)
And funny enough the treats hobbit belt is bando too. Well I'll be.
It has amazing tolerances as well.
So yeah. Bando rules.
