Really no complaints. Shipping preference to AK has always been flat rate priority mail. Item was in stock @ Corona but not Wasilla where I live. After a week and item not in the mail, I called and informed that Origin was indicated AK facility and evidently would be sent to Wasilla and then mailed to me. I indicated mail to me direct from Corona and I had it in 4 days. Was informed that in the future, check mark facility(origin) to be sent from. Evidently the order form had defaulted to Wasilla.

Works perfect and high quality. Needed 14mm for Carbon Cub SS. Engine does have 18 mm to 14 mm reducers in engine block however, easier just to remove 14 mm spark plug.
