Bird B Gone MMBS800SPN 8 ft Spinning Spider Bird Deterrent - Steel

Everything it advertises is correct,, just make sure you purchase one that is big enough, as that is key!

Perfect! My boat is now free of gulls!

This clever device has kept seagulls off the top of our boat for over 10 years. This is our third one because one ended up in the drink when we forgot to take it off the roof when heading out and the other one eventually wore down - broken tines. These work like crazy, not a single bird mess to clean up if you remember to put it up there when mooring (and don't forget to take it down as you are motoring away!) Great value.

Purchased 2, 8 ft. spiders for a boat lift canopy on a lake. Installed these on the sand filled base from Bird B Gone. It is an absolute must to secure the base or you will lose the spider overboard in almost any wind. Neither of my spiders turned in the wind as advertised. The mounting spindle binds with the base at the bottom because the bottom of the base isn't rigid enough to hold the spider properly upright. My spiders easily flop around in the base in breezes. The spiders worked for seagulls, however they will land in any space not covered by the spiders. Had a 18 -20 mph blow between fronts and one spider broke open and dumped most of the arms into the lake. This is a poorly designed, poorly tested, unreliable product. It is overly priced and does not perform and hold up as advertised. I reached out to customer service to ask if my device is repairable, and got no response.

Wanted to keep seagulls off the Bimini of my boat. Spinning Spider did the trick.
