FlexCore Dial Adjustable Dumbbell Set Review

Design & Finish

A black steel core with a gray urethane coating. The head is bigger and more angular than a standard fixed dumbbell, which felt a bit clunky at first — but it made sense once I understood the shape is what lets the dial selectively lock onto different weight plates.

Setup & Usage

No assembly required — just set it on the stand and turn the dial to your desired weight. Turning the dial moves a pin that locks onto only the selected weight plates; the clicking sound felt unfamiliar the first few times but I got used to it quickly.

Performance / Real-World Testing

The biggest upside is how fast you can transition between sets. Going from squats straight into shoulder press used to mean hunting for a different pair of dumbbells — now it's a 3-second dial turn. It actually made resting between sets easier to manage precisely, too.

That said, since the lowest weight starts at 2.5kg, it can feel a bit heavy for rehab exercises or very light stretching. Worth factoring in if you're new to strength training.

Durability, Noise & Other Details

Over a month of roughly 5 uses a week, I didn't find any scratches or peeling on the urethane coating. That said, turning the dial to the max 20kg setting started feeling slightly stiff — not enough to affect use. The mechanical click when turning the dial could be distracting if you work out early in the morning in a quiet house.
