They’re pretty slick for saving space, and fast weight changes are a game-changer mid-workout. Just know they’re a bit bulkier than regular dumbbells-think wielding a loaf of bread instead of a banana. Fine for most lifts, but they can feel awkward for stuff like goblet squats or overhead triceps. Handle them with care; dropping them is basically SelectTech Russian Roulette. If you value space and convenience over “ironclad” feel, they’re great!
