I Called and asked basic question but was told I can not be helped and was referred to sales, which was closed or out of office. I emailed sales and received zero response. Not what I expected.

Greta, fast shipping and had the item that was hard to find at a good price.

Quick and easy check out

Gracias recibido el pedido en tiempo y buen estado la mercancía

The item arrived three days after I ordered it very fast shipping thank you

Website was confusing on my phone. Had to retry several times to get shipping to change.

These were long enough, unlike the first ones I ordered. Six foot doesn't do the job for even the smallest boats.
