Love It
It works perfectly! I needed a scale that went down to a .001 oz and it does...it came calibrated. Totally worth the money. Thank you!

17 piece weight check m2 kit
I like that I can check my balance beam scale for reloading, Especially rifle loads, very critical for accuracy.
The set is easy to use.
Thanks, Tony Luzzi

I can't rate this product because I ordered the wrong thing and had to send it back for credit. Paid shipping to get here and shipping to get it back. Big loss for me but it is my fault for not knowing what to order in the first place.

works for me
I just wanted a few small weights to set spring tension on the keys of a small pipe organ. 5 gram increments would have been OK. Got much more than I needed, but the price was right. My only complaint was that the 5g weight wasn't flat on the bottom, so I ground of a few mgs!

Great product and an even better retailer.
I bought this set of weights to check the accuracy of my reloading scale. Unfortunately, the set came without the plastic cover for the wafer weights. Fortunately, after one call to Will Knott, a shiny new cover arrived at my door step in about 2 days, no charge. Unbelievably great customer service! The weights are good too.

17M2 piece calibration weight set
A good value for my needs. All weights within specifications except for the 2 mg (2 included) and 1 mg weights. The 2 mg weights came in at 2.015 and 2.025 grams. The 1 mg weight a dismal .830 grams. These were tested with an electronic powder reloading scale and a precise diamond-weighing (carat weights) balance scale.

We know you have a choice when you buy scales online. Just know that when you buy digital scales from Old Will, it's always a "Worry Free Deal".
