order 100 gram weight... But received a 50 gram weight instead

The plug fell out and the "bbs" were lose. I could not get them to balance at 100 grams by putting them back in. One must have been lost in the packing. The plug would not stay in. I have other weights to equal this so it wasn't worth my effort to return.

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.

100 gram calibration weight
Nice packaging nice looking calibration weights however it is off by .237 being that I am disabled and have to accurately weigh some medications it is a hassle to do the math to make sure my doses wait regiments I have also tested this product that I have purchased on 5 other 100g micro scales and a Triple Beam scale and they all agree that this calibration weight is off within a tolerance of .237 and .2 41 I kind of found that undesirable but overall looks good and reasonably priced I just wished it was a little bit more accurate

This Product was delivered quickly, but the shipping envelope tore in shipping, and the product was lost. I contacted Customer service, and they re-shipped the product and it was here in just a couple days. I would recommend this company to anyone. The product itself was exactly as advertised, and was less expensive than lower quality ones elsewhere. I am very happy.

Arrived with bottom plate off and weight fallen out
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.

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.

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 weight
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 Service
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.
