Does anyone who has used this for electrical purposes determine what kind of current this tape can handle?

I'm surprised the manufacturer doesn't seem to state the current rating of this tape. Fortunately, it can be determined fairly easily. Current rating = Current Density * Cross-sectional area I measured this tape (1/4") to be 6.2mm wide and approximately 0.1mm thick. I made efforts to remove the glue with both Acetone and Rubbing Alcohol, but I was not completely successful, so the thickness measurement does include at least some of the glue. So, 6.2mm * 0.1mm gives us a cross-sectional area of 0.62mm. NIST Seems to use a current density of around 2.8 for Copper, so I'll do the same: 0.62 * 2.8 = 1.736 Amperes However, NIST uses very conservative values in their calculations. So let's round up to 2 Amps. To test my calculation, I took an approximately 4-inch piece of the tape and connected it between the terminals of my bench-top power supply. The tape was not attached to anything else, I left it floating in the air between its two connection points. I made sure no fans were running and turned off the Air Conditioner/Heat. I also took efforts to not breathe on or in the direction of the tape. Overkill? Perhaps. What I'm testing is to see if the tape significantly increases in temperature when exposed to 2.0A of current. Before applying power, I took a temperature measurement of the tape @ 72.0F (22.2C) using an infrared thermometer with an Emissivity setting of 0.95. I then set the bench top power supply to 12V @ 2A (voltage doesn't really matter here, but for sake of completeness...) and let it sit for 5 minutes. I took a temperature measurement about once every minute, but saw no gain in temperature. After 5 minutes, the temperature was still 72.0F. Immediately after removing power, I placed my finger on the tape, which felt slightly cool to the touch. Given everything outlined above, I'm pretty confident that it is safe to run 2A of current over this tape for long periods of time. I used pretty conservative numbers, so it is likely safe to go a bit higher even. However, if you want a good, safe limit, then 2.0 Amps seems to be a good number.

will a magnet stick to the tape? If so, how powerfully?

A magnet will not stick to the tape because copper is effectively not magnetic.

Has anyone used this to prevent slugs from getting in flower pots?

I haven't yet but come spring, I plan to try it out. Slugs hate silver foil which I have used in my own garden to protect a patch of early black eyed susan transplants that these pests just love to eat. I will try the copper foil tape around the base of clay pots as suggested from information I read about the many uses of this foil tape. Sorry I dont have an exact answet for you. Happy Gardening.

Can i use it to fix a rear window defogger tab in my car?

Yes. It has good electrical properties. You will have to solder it, since the adhesive backing does not conduct.

Bought this for wiring

Works great. Real copper. The adhesive is impossible to get off, making it less than suitable for my needs. Still 5 stars because it's exactly as advertised.

Non conducteur

Ce ruban est parfait pour les projets d'arts, il adhère bien et est facile d'utilisation. Mais si vous l'achetez pour faire des circuits achetez autre chose car il n'est pas conducteur comme stipulez dans la description. J'aurais dû faire un test plus tôt pour pouvoir me faire rembourser.
