Recently purchased wakespeed alternator and was impressed with the prompt service and order fulfillment. The unit was well packaged and using USPS for delivery here in Western Canada saved me the typical huge customs brokerage fees that ups and fedex charge.

Purchased REC 16s BMS from Off Grid Marine Energy systems and did not purchase the current sensor wiring harness, I emailed asking if it was meant to be included and they threw it in for free. When I had questions about shipment they were answered in a timely and polite manner.
