Okay, so I needed this specific battery for my fancy electric window shades (yes, I'm that person). Couldn't find it anywhere except Amazon - lifesaver!

First impression? The packaging is SUPER child-resistant. Like, I almost needed help opening it myself. Safety first, I guess?

Popped it into my shade controller and boom - instant response! No lag, no issues. It's been running smoothly for weeks now.

Love that it's guaranteed for 10 years in storage. Mine had a 2021 copyright but warranty until 2032 - math checks out!

Only downside? Saw one review saying theirs died quickly, but mine's going strong. Maybe they got a dud?

Overall? 5/5 would recommend. Tiny battery, big power - exactly what you'd expect from Duracell!
