First class service and the battery fired up first time. Appears to be very good quality with plenty of power to crank over the large V twin.

Had used one of these for a short while which I was impressed with. Sadly bike was written off,so just purchased one for my streetbob and so far so good! And so much cheaper than a genuine HD .

Outstanding. The WestCo is ideal for a big V-twin. I barely have to stroke the start button and my twenty year old Wide Glide bursts into life. Definitely the best yet. Fits the battery tray perfectly. Just make sure you get the version with the positive terminal on the correct side, as they do two versions and the bike's cables aren't long enough to accommodate the wrong one. Highly recommended.
