Review on 🔋 Tenergy TN299 Universal Battery Charger: Smart Charger for AA, AAA, C, D, 9V, 18650, and More with 4 Independent Charging Slots by Elizabeth Keever

A lot of people love this charger but my experience was just the opposite. Its ergonomics are terrible: you can't read the battery gauge graphic or switch positions. The battery charger sliders sound intimidating and are so poorly designed and manufactured that they are difficult to use in the first place. The worst thing is that the latest charger now rates almost new Tenergy NiMHd batteries as bad, while the chargers from other manufacturers only rate them as good. So I don't know if it's just a quality control feature of my bad device or their design in general. But I certainly wouldn't recommend this expensive device to anyone based on my disappointing experience.
