Amazon Basics Wood Wobble Balance Trainer Board - Core Strength & Stability Training for Kids & Adults - Perfect for Home Gym, Office, Yoga & Physical Therapy

Cons:> It looks basic, so it doesn't look fancy and is not selfie-worthy for your social media.> Agree with some negative reviews that it could hurt your crybaby feet if you didn't wear shoes, and could potentially hurt your ass, if you sit on it naked.> It can be dangerous if you fall off it, just as it could be dangerous if you fall on a deceptively flat floor.> It could be a little bigger for some bigger folks, but at that point, you need more help than this do hickey.Pros:> It is a solid product, but I would image the plastic can wear off over time if you have sandpaper for flooring.> It works out my core and has inadvertently improved my balance(or at least it feels like it).> It is very affordable for $20.> It is fairly easy to transport, light and about a foot and a quarter across.> It works great on carpeted floors(logic says it may be slippery on smooth/ glossy ceramic or vinyl tile (but what isn't?!).> Could still use it for your "basic bitch exercise snack selfie".
