Unit works as described, good service from Go2Marine


Unit works as described.
<br>Go2Marine / LFS shipped the product very quickly so it arrived earlier than expected. Good service so far.
<br>As for the product, it works exactly as described, though from a design perspective it would be better if it was in its own project box to protect it and cables available to make the appropriate connections. A fan speed controller which it does not have (fan is on or off) would be a good enhancement.
