Could use a better box but it comes with a box that does its job nothing fairs well if dropped. Mine is pretty much stationary so I’ll probably never need a second set unless I’ve lost pieces. Bad comment is cheap tweezers get what you pay for so get a better set if you want to look professional while using

This is a GREAT set of weights! My scale goes to .001 so I seriously researched accurate weights for almost a month before I bought these. I purchased these in May 2020 and have been using them daily since that time. At .001 just the shifting air (like from the a/c or you breathing on it) will affect your reading, so my scale has a lid with a little hole in the top to allow you to pick it up. I have to cover that small hole for true accuracy or it will drift. I also calibrate it every single time I turn it on.These weights have been dead on for me with no drifting if I'm using the cover with that hole blocked. They are excellent!My only is with what surrounds the weights. The case is super cheap stamped plastic with a tiny piece of "cushioning" glued to the lid to hold the weights in place (see pictures), so it arrives with everything rolling about inside. The mg weights (which come in a tiny zipped plastic bag that the tweezers hate - we'll talk tweezers next) fit very awkwardly into the small spaces at the bottom, and the clear cover over them doesn't lock into place. Drop this thing and you'll be sorting everything except the 20g-100g weights in the back.The tweezers were built for TODDLERS. They are a ridiculously thick plastic that bends (literally) if you use them to pick up the smaller gram weights, and while I fought and eventually succeeded in using them to pick up the MG weights a couple of times, it just wasn't worth the battle. I use different tweezers now. My picture shows ordinary everyday tweezers from your local drugstore in comparison to the included tweezers for a better size reference than the odd tweezers I use.I definitely reccomend the weights! I would, however, find someone crafty to build a new case to keep them in or go find an empty weight case with better cushioning to house them. Mine is being created from wood as a birthday present from my wonderful husband!

Great product it's all I can say just easy to use.

all others good. 2g is off by 0.15

It’s nice to have a set of these for my own personal use. This was great for the money. The set is good to use at home and not have to go back into the store I purchased from.

It came quickly but these things are so small, with the callouses on my fingers they are impossible to pick up. The 100 gram weight is right on compared to the state inspectors.

These were not as accurate as I was hoping, but a decent value. So I will keep them. The smaller weights are small rectangles of sheet metal with a bent corner. It comes with a very cheap pair of tweezers that works OK but not great.The small rectangular weights are not well labeled, perhaps not at all. My eyes aren’t what they used to be, but I am wearing reading glasses.

Had no problems the weights were spot on
