i dunno how well they work but every time i use my binoculars, i always wish i had one with image stabilization, especially at higher magnification. if they work well, maybe 12x image stabilized would be good for bird watching?

No ,
$100.00 I.S. , 12 x power binos would not be a good investment

My wife's birthday was yesterday. I got her a 23 & Me Kit. She was intrigued and liked it.

What ever you need in my world...

status ?

Depending on what birds she is most intrigued with and your location,maybe a day or overnight trip to somewhere she might see some different birds or a bird club membership. I know in this day and time, vacations/overnight stays are not the most optimal unfortunately.

Louis Vuitton purse.

Yeah,
I don't ever want to be the guy who give's the love
of his life
$100.00 Luis Vuitton hand bag.

For an inexpensive gift as an add on to something more expensive you might get her a Road ID.

They make an engraved plate with name, contact information, and any medical information you might want others to know should she take a fall.

I have one of their "sidekicks" that fits on my watch band.
