This weight works great fantastic company to buy from

I needed a 200 gram weight. Found this one and all my scales show that it is exactly 200 grams. Works great

Thank you

Excellent product, very low price, and fast delivery. Couldn't ask for more!

The 100g weight has a small circular plate on the bottom and inside is a ball-bearing which adds about a gram. When the order arrived, the plate was off, and the bearing was floating around inside the plastic bag. Not a big deal as I just used a dab of superglue to re-attach it. Also, not a big deal because OldWillKnott gave it to me for free (I asked about calibrating my scale and they recommended a 500 and 100 weight which I ordered, but turns out I had an older model which only needed the 500. Thus they kindly just credited me the amount for the 100g saving me the trouble to ship it back.) 4 stars for a combination of great service and an easy to resolve problem despite the quality issue.

Wanted to know how accurate a new digital scale was that is supposed to have a +/-1 gram tolerance. Ordered this test weight and it comes up as 99 grams so either the test weight is off by 1 gram or my scale is but either way it is within tolerance.
