Great price and fast service!!

Very good website!

It's the information I needed for my boat motor. The only issue I had with this maintenance manual was the way the manual was finished. I've worked the the graphic arts industry for 50 years and am well versed in print finishing. The book will no doubt stay together, however there is excessive glue on the spine as the cover wraps around the front/back that distracts from the overall appearance.

Thank you

Fast, easy, hopefully trust worthy. Upon receipt of order, I'll up date my comments. Thank you.

Product was delivered in a timely manner in good condition and was easily installed. I would order again!

Shipping cost was too high for the length of time it took to be delivered.

Excellent. Fast and accurate.

Had what I needed at a fair price.
