Almost like the original I'm satisfied; it's not too difficult to install. It's a bit difficult the first few times. But after a week, it's back to normal...

Fits perfectly It fits well, and the instructions are clear. You need to thoroughly clean the silicone from the gate frame before installing the new seal, especially on the curves.

Received today and still needs to be assembled I bought this seal by the meter to replace my LEWMAR side porthole seals. The seal's profile isn't exactly the same as the original one, which dates back to 2003. That one was a simple lip that made contact between the plexiglass and the frame when closed. This one looks more like a thicker bead that compresses when closed. The previous seal hardened with age and eventually lost its watertight seal. With this replacement model, that shouldn't be a problem. Now I just have to install it. The instructions are clear, and the reviews I've read show that with patience and a bit of skill, it's doable. Now I just have to get the job done.

Lewmar window rubber, porthole
It is not exactly the same size but matches almost perfectly. Fits well in the profile. Slightly too short on the outside for a drainage outlet.

Price performance is right
It's extremely difficult to close the hatches after installation because the seal has to give a little bit first, but otherwise it's fine.
