Excellent Product and Service
I purchased a 200gm weight from Old Will Knott Scales as a first time buyer. The weight was exactly as described on the website, came very quickly. The price was fair and reasonable, the website is easy to use and checkout was simple and quick. I highly recommend this company.

Calibration Wt.
I ordered one 200g calibration wt. But you need two 200g wts. to calibrate the scale. Nowhere did it say two were required the calibrate this scale. So one calibration wt. is useless. I really like the scale.
I'm the Vice President for the Comstock Gold Prospection Club here in Reno Nv. and a weighting your Gold is part of the process.

I am very pleased with this JSR-200. I am a coin collector. I like to catalog my coins and knowing the exact weight is very important to do this. Different denominations coins have a specific weight. Finding the coins that are the weight they should, I can filter out the fakes from the genuine. Very helpful! Thanks Old Will Knott

A steal for stainless steel!
What can I say, it is exactly as described-a 200g stainless steel weight-used to calibrate the balance I purchased.

I glad it's stainless steel; I don't have to worry about it rusting over time.

I'm very happy.
What can one say about a 200 gram calibration weight? Not much. The price was the lowest that I could find anywhere. I assume that it weighs exactly 200 grams. However, I must say that the online ordering process was quick, straight forward, and easy. I had the product in 3 days after ordering. It was a very pleasant buying experience, and I will definitely keep Old Will Knott Scales in my electronic roll-a-dex.

M2 Calibration Weight 200 Gram
Excellent Weight. right on the money. I tried weights from other places and messed up a scale's calibration I already owned. Then I ran across an ad for Old Will Knott Scales and found their weights and scales and was Blown Away by their prices and quality. While other places are charging hundreds and thousands for comparable weights that meet basic standards of accuracy, Old Will makes simply accurate weights at an affordable price. Now to go on to their selection and quality of scales....outstanding...and the prices cannot be beat. This site is a metrology technicians dream...Thank you Old Will.

I ordered the 200 & 400 gram weights for my postal scale and other equipment that I want to keep accurate weight on. The weights arrived sufficiently packaged with no visible deficiencies. I am very pleased with the order and the timely arrival of the product.

calibration weight
The weight arrived in good shape. I have weighed it on various scales, and it appears to be exactly 200 grams. It would have been nice if it was shipped in some sort of protective container, but it turns out that it fits perfectly in a plastic 35mm film container.

What can you say about a calibration weight with no moving parts, and really just sits there. But is that all?? Fit and finish is very nice and easy to clean. Finctions as advertised with nice fingergrip. When tested on my new My Weigh i300 (sold seperately) it weighed in at exactly 200 grams. Old Will Knott Scales were great to deal with. Ordered on line, they provided tracking numbers, delvery was on time, and products were packaged nicely. Nice prices too!
