600 pcs Heat Shrink Tubing 2:1 Wire Sleeve Electrical Wire Cable Wrap Assorted 5 Colors 8 Sizes In a Plastic Box

A great assortment of brightly colored heat shrink tubing in a convenient storage container. I haven't used all of the sizes or color combinations yet, but the ones I have used performed exceptionally well with an even shrink rate to a smooth finish with solid strength - I actually used one of them to repair my broken RayBan sunglasses when the arm had broken off completely from the frame. It would appear that the shrink ratio may actually be better than the 2:1 stated. A big selling point for my purchase decision vs all of the others was the "UL Recognized" statement.

nice variety, reasonable cost, works as it should

These are 2:1, no adhesive which is just fine with me. I have used many in this case and well, they did shrink and work as I expected. The case, while not exceptional, does keep the various sizes separated. I would not want to drop this case, or knock it off the bench for fear of spending hours picking up all the tubes, even if it was closed when it fell. I've used these tubes on my soldering projects and it looks good. I've also used a few tubes to coat a couple of my screwdrivers to provide insulation on the shaft.

Item arrived promptly and as described. The multi-compartment hard plastic case is very useful.

Good value, excellent selection of sizes. Only negative: one latch on the box was broken. Not a big deal.

General electric work, item is ok, not top shelf

Good value great variety. No quality issues.

You get what you pay for. In this case, you receive a decent variety of sizes and colors for the price but it's pretty average quality. I double wrapped most of my work because of how thin the tubing was. My low powered harbor freight heat gun on the LOW setting would burn the tubing if I wasn't extremely careful. Don't apply heat any longer than a second and quickly your heat gun and just keep repeating that process until it's fully shrunk, otherwise you will burn it. But I kind of knew that before purchasing a 600 pc set for such a bargain. I also found their sizes to be very odd, there's a ton of tiny pieces which are hardly used (for me, at least), and a decent amount of mid-sized and WAY too many larger pieces, the jump is just too much. It's something like, 1mm,1.5mm 2mm, 4mm,10mm. (off the top of my head, not factual) Not very well thought out sizing IMO. But you may love the sizes. Again, for the price, it's not a bad deal and I don't regret my purchase although I will be ordered the adhesive lined thicker tubing next time, I think it's worth the extra $ for my application. (Mainly used to cover solder joints on car audio systems) Remember, use the low temp setting on your heat gun and quickly move it on and off to avoid burning the tube.
