I can’t say for sure on this exact model, but I’ve compared two different Bonvoisin scales, a Four E’s scale, a US Solid and another similar inexpensive scale with a high end calibrated Mettler Toledo Analytical Balance Scale that was in use and I was very impressed with their accuracy except for one scale that I can’t remember the name of. All these scales were accurate to within about one percent up to 200g for the quick down and dirty testing I did.
Please note that I did not check for drift over time or at varying temperatures and I only checked them at 50g, 100g and 200g using known calibrated weights (not the cheap weights on Amazon or AliExpress). I did make sure to use the scales in a good working environment temperature wise, and let them warm up for about 20 minutes before calibrating and comparing them.
I believe that many of the scales that look alike are likely made by the same company and OEM’d under different brands. I use an inexpensive scale for the quick down and dirty stuff of certain raws or supplement powders because it’s much easier and quicker to use and it’s accurate enough for my needs. I only use my expensive Mettler Toledo when I truly need the extra precision.
For supplements or weighing raws like cyp, nandrolone, methenelone, etc, these 0.001mg scales should be plenty good as long as you get a good scale. If you’re weighing something more critical like T3, or Finasteride, etc, then you’d better make sure you’re using a 0.0001mg scale that’s dead on.
