Only one slight drawback is the range of the remote control works within a room only, although the technology used is capable to use it within anywhere in a house

The range is not great, but if used in a car, it works everywhere...including in the trunk!

It worked as advertised, except its useful range seems to be about 5-6'

The range is good enough as well

The range is good enough as well

The range is sufficient for any reasonable person, though.

The range, as others have said, is limited

I suspect that local interference with the RF signal affects some users who find they do not get good range

A 4 rather than a 5 because the useful range is just a few feet less than I would like.

TEC jacket as well as on my motorcycle and mountain bike.
