The time I purchased mine the item location was being advertised in the States,but it came from China. Not bothered so far, but when it came although it looked identical and the sprocket was perfectly the same, it could not slide in the starter shaft. I compared with the stock one and even both having 31 teeth they do not alighn with the shaft teeth. Tryied using some grease as a last resort but no joy. maybe they are good manufacturing electronics but never mind mechanical equipment.
