Easy to purchase, received my product rather quickly and on time.

Great. Quick

Found what I needed easily. Free shipping- yay!

Purchased a Dometic 16K AC retrofit unit to replace one that died after 20 years. Price for unit was comparable to other sites, and these other sites did not have the product in stock. Other sites were not specific on when part would be available. Boatplicity offered the best price for available stock. Part arrived as promised and delivery was on time. Arrived in excellent condition due to careful shipping packaging. AC unit has been installed and appears to be working well. Thanks for your assistance. Will use your site again for future purchases.

Very easy to order and quick delivery time. Very Happy
