Smart USB Charger with LCD Display

I picked this up a couple of weeks ago to help with my DIY projects around the house, since I'm always using rechargeable batteries for tools and gadgets. It does the job of charging multiple batteries at the same time, which is a relief—no more hunting for charged ones in the middle of a repair. The little screen tells me the status, which is helpful, but I wish it were brighter or easier to see. It feels like it takes its time to fully charge some batteries, and I've had a few instances where it didn't recognize a battery properly, which was frustrating. Overall, it's a decent tool that gets the basics right, but it's not perfect. I'd recommend it with some reservations, especially if you're patient and don't mind keeping an eye on it.
- Pros: It's fairly handy to charge several batteries at once, which saves me from swapping them out constantly. The screen shows what's happening, so I don't have to guess if they're charging properly. It's small and doesn't take up much space on my workbench, which is nice for keeping things tidy.
- Cons: From what I feel, it doesn't always charge batteries as quickly as I'd like, and sometimes it seems a bit finicky with certain types. The display can be hard to read in bright light, which is a bit disappointing for something that's supposed to keep me informed.
