I've already recommended you to my marine industry contacts. Excellent shopping experience. Your unit price was higher than average retail for the same product, but within 10% of the rest of the market and the product was in stock, so not thrilled about the extra expense, but not hateful about it either.

Good pricing, quick shipping.

EASY AND QUICK

Product and sales help were great. Shipping was a bit expensive even without requesting expedited service.

Easy to place an order and a good price

Great prices and quick shipping but I never got tracking information so I didn't know when the packages were coming.

Shipping was slow, but not their fault

Great deals on my first order
