Arrived with bottom plate off and weight fallen out4 stars

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.

M2 100 Gram Weight5 stars

I purchased this with my scale in order to check it for accuracy periodically. I also purchased the 200 gram calibration weight, in case I need to re-calibrate. Glad I purchased both with my scale, it is nice to have them if needed, and to test the scale periodically.

As described5 stars

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.

Pocket scale and calibration weight5 stars

This company is by far the most customer service oriented I've dealt with on the web. The products are excellent and the prices are right. Shipping could not be better. I will do business again with this company and I highly recommend them to everyone.

Excellent Product -- Amazing Service5 stars

The 100g calibration weight is exactly what I wanted and the service was more than I expected. I placed my order on a Tuesday and the package arrived on Friday. Unfortunately, the package had been shredded during shipping. I called the help line and, at no charge, they sent me another. I can certainly recommend doing business with Old Will Knot

I ordered the 100 gram weight when I bought my jewelry scale. Both products were delivered super fast even during the holiday season. Using this weight I can easily prove to myself an scale is measuring correctly.

Questions and Answers

Q: Do I use this to measure the weight of powders and such for making cosmetics or bath salts and such? Thank you... Asked by: Linnie Heaverlo (5/13/2015) answer this question

A: Hi there Linnie,

The 100 gram weight would only be used to check the accuracy of whatever scale you are using.

It can also be used to re-calibrate the scale, as long as the scale in question uses 100 grams of weight to calibrate properly.

Take care,
Brandon
