Rice Lake 12767 Cast Iron Painted Grip Handle Test Weight, 10kg Mass, NIST Class F

I have 2 Rice Lake Weights and 1 Troemner. The Rice Lake seems to be better quality. 1 of my Rice Lake weights is NIST certified(the ones sold here are NOT certified.) The 10KG that I purchased is amazingly accurate, certified at 10.0000217kg. Crazy accurate. I will buy more of these for sure. The surface of the weights is quite good on Rice Lake, but it's cast iron so expect a rough texture.

Buena calidad y peso correcto

it was ok, but I ordered a 20lbs and got a 10kg , not the same at all. I sent it back. if it was the correct weight I would of kept it.

Needed as a backup to an electronic scale

I purchased these scale weights to work on various grip and strength training exercises. By using magnets and smaller weight plates, I can increase the overall weight to accommodate different exercises. I am very happy with these.

Quick turnaround (delivery w/in two days), and the 25kg weight measured in at 25000.3/25000.4 on a 32000g MAX ±0.1g calibrated scale.

I ordered the 10 kg weight. There was damage to two corners of the weight I received (missing paint and scrape marks), making it questionable as a calibration standard. While the shipping box was undamaged (though lighter duty than it should be), the product box inside had serveral tears in it, and the product box was also longer than the weight with no padding inside to keep it from shifting around. These need to be boxed better to keep them from being damaged during handling.

I had the weight weighed on a certified scale and it weighed 49.12 lbs. It is suppose to be 50 lbs exactly. It is not as advertised.

These 20kg weights is supposed to come with traceable certificates but came without it, so, I had to return 4 of them and reject 4. I did purchase from Amazon because of delivery time and certification as I red in the description
