I used electrical tape for several years on my road bike, with tire pressure of 100-110 lbs, and never had any problems. I only used one layer, and I don't remember if it was a premium brand or not. I read somewhere that it works well and it's light, so I began using it out of convenience (I always have a couple rolls laying around). But a couple years ago I bought a bunch of rim tape on sale at performance or REI (can't remember), so I haven't used electrical for a while. However, my personal sample of 1 says it is OK. No more/less flats, no blowouts, no discernible difference between it and high end rim tape, which I have also used. And one roll will do many, many tires.
