Nice and Shiny
These are strong and look really nice. I use them for 3D Printer upgrades. One thing I noticed, the screws do not come organized in their bins. That did not bother me. It took me 15 minutes to organize them. And for the price, how could I complain? Customer support is excellent! The brand stands behind their product. There was a supper small issue I had with the order. They fixed it super quickly! I recommend these, if you need some 2m - 4m screws.

Great product
Great product, it’s difficult to find metric screws in the US. Good assortment with multiple options! Only problem I found was during shipping the panels that separate the sizes must have come off and when the item arrived, the majority of the screws were mixed up and thrown together. Not a big deal just something to be aware of if you need a specific size

Good but may need sorting.
As far as packaging, the container leaves a lot to be desired. The little plastic separators in the case were sitting on the side of the large area of the container. The bolts were all mixed together and I had to sit and sort them with tweezers. Luckily the flat and split washers were in little zip lock bags. One benefit to them being mixed was I noted the quantities of each size. I'm happy to say I was only short one m3x12 boot. It's more than made up for in the other quantities. I received one extra 10mm, and one extra 20m, as well as 3 extra nuts, 2 extra flat washers, and 4 extra lock washers. So overall, I'd say it's worth the money. Just be aware the quantities may not be exact, and they may be mixed in the container.

Decent selection of screws for a good price
Worked like they should, decent price. Holder ok the smaller screws and nuts can float around, but they don't make there way out of the box.

Great Product and Care about Customers!!
I like the way it was packaged. It included everything, in perfect conditions, and all plastic sealed. Lastly, the thank you note was the cherry on top. Overall, very good product!!

Unfortunate Packaging - good value - but you'll have to sort them again..
I picked these because I was going through M3 screws like crazy. Good value for the quantity that I needed. As you can see in the picture though this is how they came out of the package - the top was bulged a bit so maybe some better packaging like each screw size / nuts in separate bags in each compartment. ( Maybe this was a return and opened who knows) either way. Won't be getting this again. I'll be able to measure the size to pick what I need but just a medium size pain in the butt.
