Power Systems Water Dumbbells vs Kiefer Water Workout Dumbbells

No sources that do their own in-depth testing have considered the Power Systems Water Dumbbells to be a good enough purchase for it to earn a sport in their Barbell roundups, which is typically a bad sign.

Taking a look at the Kiefer Water Workout Dumbbells, we found that it hasn't managed to perform well enough to earn a spot in any Barbell roundups done by sources that conduct their own, high-quality, hands-on testing. That alone makes it difficult to recommend.

As a last step, we wanted to do a head-to-head Power Systems Water Dumbbells vs. Kiefer Water Workout Dumbbells comparison of their review performance but, unfortunately, weren't able to find any review ratings on either product.
