Let me start by saying these PGSONIC LR44 batteries are a solid budget pick for powering small gadgets. I've used them in everything from kitchen scales to my kid's noisy toys, and they deliver consistent performance.

The value is undeniable - 50 batteries for the price of maybe 10 name-brand equivalents. I particularly love that they work in all devices listed as compatible (my digital thermometer and laser pointer both run perfectly). The packaging is secure though slightly frustrating to open - you'll need scissors for the rigid plastic case.

Now the not-so-great part: Like another reviewer mentioned, I did find about 1 in 10 batteries were DOA. Not ideal when you're in a hurry to replace dead batteries. Also, while most last as long as brand names, I had one set in a wall clock that died suspiciously fast (2 weeks vs the usual 2 months).

Storage seems fine - no leaks or swelling after keeping extras in my junk drawer for 3 months. They're perfect for high-drain devices where you change batteries frequently anyway (like gaming controllers), but I'd think twice before using them in hard-to-reach medical devices.

Bottom line? At this price point, they're fantastic for casual use despite the occasional dud. Just don't expect Energizer-level consistency across every single battery.
