EMS machines for recovery only: Would these do the trick?

I was looking at EMS machines on e-bay for increased capillarization and recovery only. These seemed the most appealing:

This one looks like it might be a bit more powerful.

This one is particularly appealing because it can cover a variety of muscles.

Both are appealing because they are not big investments. If you reply you don’t necessarily have to know the models but just be able to relate some experience with some machines like these and whether they would be powerful enough to stimulate recovery (I understand the fat women issue, but fat women are also not looking for as intense a stimulus as we might want for recovery).

Sorry to bump so quick but there’s only nine hours left on the first one!

Don’t bother with an ems unit.

Why not use EMS?

Even just for recovery and if massage is not available? Why?
