Seems to work.

Now for drinking the beer.

Umm, you know that is a twist-off cap, right???

You dont understand how research and development works.
Yes it is a twist off cap.

A bottle opener is only truly effective when you see two bottles and it still works.

Are you suggesting an endurance and durability test? I think I am up for that.

I think it's the only way to throughly test your product. Follow the words of a wise man

"Sometimes too much to drink is barely enough."
Mark Twain

Twist-Off? TWIST-OFF?

Everything that is wrong with America in one and a half words ...

I once went to a girl's house, we were pretty drunk, she went to the kitchen for more wine. It was taking awhile. I went to investigate. She was very frustrated and couldn't get the wine to work. She was twisting with the corkscrew, around and around. It was a screw off cap, that now had a nice hole in the top. We got to the bottom of the problem and promptly finished that bottle too.

happy to do some field testing if needed

I agree, field testing is in order! And just so you can properly control the parameters of the field test, you should send out both the opener AND bottles to try them on.

if you need a test at a different elevation, I can help here in Wisconsin. UPS to Greendale WI.

We can test it together where beer is king

can you do a bunch with our logo on them so we can give them away with orders?

That looks like one of Pete's key fob's, slightly modified, from Restoration Design.

Sort of. I had his copied and used 11 gauge steel for more strength.

Thanks for all the filed test engineers who stepped up to offer free testing.

I think my testing is conclusive. Problem with the test is the test operater becomes less capable as the product is repeated used.

Ron (Slits Meier), once remarked that he noticed a distinctly lower amount of work that got done and lower quality work done when we got together and greater amounts of alcohol was consumed.
Who'd a thunk ?

I now have the can opener cut out in the laser curt out design. Planning on running a batch for the swap meet.

Need a vote as to plain key fob or with bottle opener ?

Bottle opener. Oscar is coming out with the leather fob's in a few weeks.

You need to get an award for selfless dedication and bravery. Perhaps a medal that will open beer bottles. It is a proud moment for us all.
