Rechargeable Battery for Smartwatches

i picked this up a couple of weeks back after my old battery kept conking out mid-day, and it's been a game-changer, the performance is reliable, no more frantic searches for a charger, and it holds up well through my freelance work, though i wish it came with clearer instructions or something, overall though, it does exactly what it promises and keeps my watch ticking without any hiccups, highly recommend for anyone tired of constant recharging
- Pros: finally a battery that actually lasts all day without dying on me, it fits perfectly with my watch and charges up quick, the capacity is solid so i don't have to worry about running out of juice during long shoots or meetings, and buying a pack of several means i always have a spare ready to go, which is extremely convenient for someone always on the move like me
- Cons: it's a bit pricey compared to some others i've seen, and while it works with many models, it might not be a universal fit for every smartwatch out there, so double-checking compatibility is a must before buying, as it seemed to me
