Since it looks like you'refishing for some constructive criticism - I'll playsome devil's advocate.

Here are my real concerns about your toy. First, as you described it, there's no way to disassemble the housing to clean/replace the old disc. TIP: We like fresh scents - not stale buck pee from 3 weeks ago. Being able to clean the wafer isverymuch necessary.

In addition, there's no advantage to using that device over(cheaper) scent wicks (3/$2.99) or old tube socks or shredded ragsthat have been washed in scent-free soap (free) - which is what I use at this stage in the game.

Finally, it doesn't look like it will benecessarily air-tight when closed - which leads me to believe that if you really saturated the foam discinside, it may actually get a little sloppy around the port cover.

I've never had a problem with my scent bottles leaking - the lids screw on and stay on.

There are already about 9 million scent dispensers out there, and this one is no different than the others.

For a Stealth disc, it's not very stealthy, either. It's NEON ORANGE. If you wanted it to be easy to find after dark, you could have just made it camo, and stuck on a dot of reflective material - like those cat-eye glow tacks.
