Bests & Worsts Reviews from Amazon

These are high quality silicon insulated wires. Description mentioned max temperature only 150C but it is actually 200C stamped on the wires. It is important because during soldering they don't burn like cheaper PVC insulation. These wires are the best for the soldering prototyping board - flexible, low impedance and not burned insulation. Deal is good too. Don;t confuse this set with cheaper one which has PVC insulation. It is important because during soldering they don't burn like cheaper PVC insulation. I attached here images of how I setup this wire box. The goal is to prevent entanglement between spools wires while you use them. If not doing it right it is even hard to place spools in box because wires get entangled . 1. before putting spools in the box place sticky tape on the top of each spool to prevent entanglement while setting up (picture 1) 2. after putting spools in the box, drive wires through the respective holes according to the color, then prepare a folded piece of carton to place on the top of the spools 3. now you can remove tapes from spools, place folded carton on the top to keep spools pressed and wires kept in the spools and fully close the box (picture 2) 4. tape the flap of the box as shown on my pictures and end of the wires are waiting to be pulled. That's it. Now, if you did it right, the wires will not entangle , pulling will be smooth, work is easy. (picture 3) Enjoy
