I was looking at harmonic mounts and came across this comparison. They are made by Umi (could be any manufacturer really the brand is not important)
In terms of specifications the umi 17 vs the umi17se is the reduction ratio
(500:1 vs 400:1) the payload is identical etc.
Is there a reason or a benefit of one over the other? I have seen this on other mounts as well.

The 1:400/1:500 is the final drive ratio between the Strain Wave Gear output and the motor input, This ratio would also take into account the SWG reduction and any reduction in getting drive from the motor to the SWG.
If i were a betting man, i would say that they've either:
- Changed where they source their SWG from, and have to change out of necessity, or
- They've recalculated pay load limits and can get away with a smaller SWG unit to save some manufacturing costs.
