Review on Amlits 205PCS 304 Stainless Steel Rivet Nut Assortment Kit - Threaded Insert Nutserts Set with Flat Head for M3-M10 Sizes by Jeff Vasquez

Good: The threads are the right shape, the right size, and quality workmanship. Case of decent quality. Disadvantages: very blunt notches. Incorrect caption. This set contains what is listed in the description, not what is printed on the box. M3, 4, 5, 6, 8 and 10. On the lid of the box (shown) is M12 which is not included. All labels on the cap except M3 and M4 are inaccurate. The box/case for such a set is of good quality. Many other off-brand kits have bodies that break or deform easily, are too flexible, etc. Despite marking issues and questionable long-term "gripping" in holes due to lack of blunt prong bite, these inserts appear to be, and have, decent quality good value for money. If any of them spin or break I will update the review.
