2Pcs Gel Blaster Upgrade Spring 1.2/1.3/1.4/1.5mm

They seem to be exactly what they were described to be. They are a tiny bit shorter than the SHS springs that I have, but I'm not sure how that will affect their performance. I will install them ASAP And review further.

I ordered a 1.4mm spring and then gave me a 1.2mm spring. It says they ship 2Pcs but they only sent me one spring. Do not recommend buying.

As described, just slow shipping, can’t complain.
