                  Rated 1 out of 5 by from They don't last longer than 2 or 3 years I bought mine in 2016. By 2018 they stopped working. I oiled the fan with very expensive clock oil and changed the battery. It lasted a little longer but not useful. I liked it in the beginning but they don't offer replacement motors so it is now a very expensive nothing.

                  Rated 1 out of 5 by from Same as other reviews. I’ve purchased two. Neither lasted more than two years. Battery not replaceable and they start squeaking as the tiny fan motor wears out. Neighbor thought my boat was going to catch on fire. $10 per month seems too steep. If they can make ceiling fans last decades, surely can do better than this.

                  Rated 1 out of 5 by from Can't give this zero stars, so... I replaced a very old Marinco solar vent fan that worked for many years with this version. This fan probably worked fine for a week or so. Then I noticed that I had to flip the switch in the mornings to get it to come on. I thought it was the battery running low overnight. Nope. After months of doing this every morning, I covered the solar panel one night and in the morning flipped the switch to start the fan, and it ran for a few hours with the solar panel covered. It had a charged battery but for some reason, just randomly (but every day) is not working. I would not recommend this fan and would give it zero stars if that was possible.

                  Rated 3 out of 5 by from Catalina 30 Installation / Use Experience I needed better passive ventilation in my new (to me) Catalina 30 sailboat (1989 Mk II) while sitting in her slip. I installed this in the small clear hatch just behind the mast. Installation was easy, and the fan spins up. However, it does not have the air flow to make much of a difference, especially in the 90+ Deg F temps we've been experiencing (inside temps over 100 Deg F). I suppose it's better than before but I expected the fan to draw more.

                  Rated 4 out of 5 by from Great for exhausting air from the head. Have used these for years. They are great at gently exhausting air from the head. A proper size holesaw makes the install easy. Test the unit before installing. Put it in the sun for an hour and then turn on the fan. It should run virtually noise-free. If it makes noise, it is defective. Return it and Defender quickly will send you another at no charge. Took a star off for two reasons: (1) one of two units was defective and had to be exchanged; and (2) a jib sheet can get caught under the edge of these redesigned units.
