Honestly better than I expected for the price. I’ve tested it against my high-end multimeter and the readings are surprisingly close. It handles everything from AAAs to those weird button cells which is a huge plus since my old tester was super limited. The build feels a bit plasticky but it does the job well.

Honestly way better than I expected for the price. I've been using one of those cheap analog ones for years but this Dlyfull is way more accurate and handles everything from my rechargeable AAs to those weird little button cells in my car remote. Tbh, it saved me from throwing away a whole pack of batteries that were actually still good, just the device was finicky. Super easy to read too.

It's okay for the price point but the build quality feels a bit plasticky, kinda like a toy. It works fine for standard AA and AAA, but I had a bit of trouble getting a good connection with the 9V terminal. It's a decent budget option if you just need something basic for around the house, but I’ve used more solid ones before.

Idk why everyone likes this... the screen on mine is so dim you can barely see the numbers unless your in direct light. Also feels like it might break if I drop it once. Waste of money, should of just bought a name brand one.

I've tried a few of these cheap checkers before but the Dlyfull is actually solid. It handles everything from AA to those weird button cells which is exactly what I needed for my kids' toys. The screen is clear and it feels way more durable than the plastic junk you usually see at this price point.

Much better than the old analog one I had with the swinging needle. This digital readout gives me a much better idea of how much life is actually left in my rechargeables. It's simple, effective, and the accuracy seems spot on when compared to my multimeter. Definitely worth adding to the toolbox.

It's okay. A bit finicky with the smaller button batteries though, kinda hard to get them to stay in place to get a reading. Tbh it does the job but the build quality is just alright.

Waste of money. The screen flickers and it gave me three different readings for the same battery. Just buy a better brand.

Mixed feelings on this one. On one hand, it's very versatile and tests almost everything in the house. On the other hand, the sliding mechanism feels like it might break if I'm too rough with it. It's accurate enough for home use but feels a bit "budget."

I honestly didnt think I needed this until I bought it. I went through my "junk drawer" and found out like half the batteries I thought were dead were actually still good!! It basically pays for itself because I'm not buying new ones as often now. Super easy to use, even for my kids. 10/10 purchase.

A very practical tool for household maintenance. The accuracy is impressive for a budget-friendly device and the universal compatibility is its strongest feature.
