I REALLY wanted this one to be at least decent. The plan was to surprise my 11-year-old nephew (and everyone else in the family) by hurling this thing out of the garage onto the Christmas tree while the Jaws theme plays in the background as we get together to open the gift . . I keep 911 on speed dial in case my mother-in-law loses it. As many others have attested, this is the flimsiest and worst design of what could have been an exceptional product. After more than two hours of tinkering with pointless bits and pieces, rubber bands and flimsy double-sided mounting tape - and having to stick a connector into the rear fin to hold the connection - we were finally able to test it. When it works, it's amazing. You don't really realize how REALLY cheap other fins and the like are. But the problem is that the double-sided tape only lasts a couple of hours, and that was using the included clear tape and our own HD tape to try and keep them in place. After our initial 15 minute test/phone video to send to friends we are on our third landing gear to be reinstalled in three days after which it just floats in the corner waiting to go on holiday. It just falls apart, just dangles. I finally have some truly industrial high-resolution double-sided tape, and while it seems to be holding up, let's not even look at it too closely for fear it might fall apart. Obviously this gift is just the thing for the crazy uncle I want to be. as well as for my nephew - I mean if we had something like this when I was a kid, WOW! At $50, the price is okay, but I can't help but wish there was a $79 or $99 version designed with real world use/durability in mind. How difficult would it be to mold the mounts into the shark itself or something better than an attachment for the stabilizer bar? I just hope it goes away some evening as I no longer see it, even with adult supervision. Hopefully, as a one-off, it will even survive the trip to Grandma's house in the minivan. If so, I'll secure my position in Crazy Uncle Shame. **UPDATE** With a bunch of industrial double sided tape, fresh batteries and a prayer, ^*#! ##$! The shark came to the grandmothers. The first 3 minutes was a letdown as you had to turn off the HVAC system to control it - I learned this the hard way when a drunk shark stumbled into a tree. After this was fixed the register worked for an hour and a day later reported that it was still working. Really the worst technical idea - you either have to glue or run a wire to the fin - many people here with this problem have to go to MacGyver and fake it. He did his job - I really want to release him outside and then get him out of the sky.
