Small Package, Big Noise
This is the second of these synchronizers we have bought for the shop. The set up is slightly different from old school mag boxes, but the results are the same.
ProsSmall package conserves precious toolbox space
ConsA volume control, or speaker "off" switch would be a nice addition. It's loud enough to be heard on a noisy ramp, but it can be a bit grating used daily in a quiet shop.
