I was amazed how fast my scale and calibration weight arrived! The scale is very high quality and very simple to use. . . . .5 Stars all the way!

Had my order in my mailbox the same day I received a shipping notification! Worked great to calibrate my digital scale

I had a 100g calibration scale from before, but found out my scale needs 2 of them to calibrate. Since discovering Old Will Knott, I would not by these type of products anywhere else. This one and the other one, weigh the same on my .01 gram scale, so that is encouraging. I was able to calibrate my scale, everything arrived timely and in excellent condition. The problem with Superstore websites, is you don't always get what is pictured or you think you are getting. Also in this case the price was more than double and even with free shipping it came out higher.

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.

Service was grate and product was shipped fast. I got my order the next day. Very happy with the product and I would order from here in the future.
