Topton Uninsulated Tin-Coated Copper Wire Ferrule Cable Crimp Terminals Butt Connector 150pcs 3 Sizes 10-12 AWG (4.0-6.0mm2)/14-16 AWG (1.5-2.5mm2)/18-22 AWG (0.5-1.0mm2) in Case

Based upon the reviews I assumed other purchasers had used environmental spices like these before... Simply put. Don't waste your money... The smallest gauge supposedly fits 18-22ga.. This is grossly inaccurate. Your easily able to fit 12ga wire.. I compared these to my raychem splices. You'll need to strip back 1-1.5 inchs (folding the wire over x4 times) to get a secure fit on anything 18-22ga wire using the 18-22ga splice.I'll try another brand and hope their tolerances are at least somewhere accurate.(wire is high quality M22759/16-12)Topton 18-22ga claims splice fits (0.5-1.0mm2)3.30mm2 wire easily fits.These would best be used for stub splices on anything 12 - 8 gauge. (6awg is just a tad too big to fit inside the 12ga topton splice.)

Great product, far better than twisting wires together.

They will arrive completely mixed up in the box, could have just threw them all in one bag and it wouldn't have made a difference why even bother with the organizer?

Great size and makes multiple splices in a small area easy with minimal bundle size increase

work great for a do it yourselfer

Perfect and easy to use!

works great
