Disapointed. To return this product to you I would need to pay 45$ of transportation delivery fees. The strap loop sewn to the canvas teared. The metal piece to adjust the long strap, skratched the pole. The canvas cannot be attached to the post with that break. Disapointed.

Bought this product to make a cheap Bimini top to work with my wake tower. Very cheap alternative, provides lots of shade, works well. Rolls up when not in use. Just have to buy the mounts separately.

Difficult to keep the front poles from bending inwards.We added tent shock cord poles to try and stiffen but ultimately gave up.A 3 or 4 bow cover much superior

Not setup to attach to existing bimini for 21 ft Boston Whaler. Existing rod holders are not back far enough & need to attach to Bimini sir support or install new bases for the Extender.

Bought this for my 22’ Sea Chaser hfc. The design doesn’t work at all for where the rod holders are located on the side or rear. One of the straps that attach to T-top ripped off when I tried to tighten it. The canvas itself seems good quality besides the straps on front. Ended up using PVC to build a frame and attached the canvas to that. Holds up a lot better.

This worked out well for our boat. It's not the simplest installation, but it wasn't all that difficult, and great considering the cost! If I would change anything, It would be the straps, they're a little difficult to get in and out of the clips. Am easy release would be ideal. Other than that, it did what it's supposed to. Holds up in wind. Perfect for a day on the water I'm satisfied with this purchase!

Can't beat this deal. Be prepared to spend a little time installing and adjusting the first time. After that it goes super quick.Straps are long so you can aadjust, once you get it right, cut and cauterize for a clean lookMine is on a 27' Grady white center console attached to T-Top.Makes a big difference in temp on boat.
