Fnoko 2 Pcs Adjustable Heavy Fitness Power Sandbag, Sand Bags for Weight, Portable Adjustable Canvas Sand Kettlebell Soft Sand Bag, Weightlifting Dumbbell for Home Training, Fitness, Yoga Workout

They work OK as a readily available substitute for dumbbells. DO NOT fill the bags with sand, the dust comes right through the fabric and will spill out of the top which does not seal. I filled some small ziplock bags with sand, but the oddly placed handle straps make it very difficult to slip them into the bags. Once I was able to get actual dumbbells, these were donated.

Rubber handle ripped after 3 weeks; the top folds to close and doesn't have a way of locking shut so it opens frequently. Not really for anyone serious about fitness. (ps I hope the working conditions for Amazon employees are improving.)

These definately are too small to allow for 45lbs of sand - making them way too light to use as kettlebells

Overall, great value. I filled each with 30lbs of sand (I made 5lbs of sand in ziploc bags and taped them shut) and they are strong and super adaptable. I have a young son (2 years) and I can keep them in the house since the weights are soft. My son has a little sand playpen and I just took sand out of that. You can buy a 50 pound bag of all purpose sand or clay sand from Home Depot for like $4. I used a luggage scale and a Walmart bag to weigh out the portions.Once you get through about 20 pounds, they can be a little difficult to get inside the bag due to the size of the handles, but if you make your sandbags a little longer and thinner they will slide through fine. If you’re just pouring the sand in this is not a problem. The top does stay a teeny bit open, so I wouldn’t recommend just freely pouring sand in.At the end I ended up with two kettle bell sandbags each way in about 26 pounds that I use day to day. I have an extra 5 pound bag of sand for each that I add in to make it 31 pounds for some exercises. I’m really out of shape, so this is more than enough for me for quite a while. The fabric can easily hold more though.

Had high hopes for these. I was pretty disappointed. Used them as kettlebells, that was an ultimate failure. The handle is way too lose to successfully complete a swing. The slack is wayyy too much. ALSO, they DO NOT stay rolled and closed. I was covered in sand. I filled one to about 15-16 lbs and the other to about 25-26lb. Both came unrolled and leaked sand everywhere. You know what’s an awful feeling? Being sweaty and covered in scratchy sand. If you do decide to purchase these, HEED MY WARNING DO NOT PUT SAND IN THERE, use rocks or weights to put inside. This is what I get for not wanting to spend the money on actual quality metal kettlebells.
