    Again five stars Extra fast, a few days from Great China. Very good price and packaging After catastrophe of quality and rudeness of the dealer (avoid) epath-brand, it is a pleasure to buy again from memolines. D.B.

    Good service after the sale. Kit arrived incomplete in 14d (w/o assembly instructions). I contacted seller via ebay. Within 24h, they sent zip file in simplified-chinese. I've translated to English (and offered them a copy). Hall sensor was not identified. I tentatively identified Hall sensor as HW101A-G.
