Nice! That's awesome you've been able to run it without problems. I haven't been so lucky. Tried both the 1Spot, and Power-All, and sadly both have had issues in certain venues. I've been gigging 15 years, and have been around the country, as well as international. It's incredibly rare, but it does happen! After having it happen once on a night where I *really* didn't need that unexpected stress, I've stopped using them outside of home/casual environments. For me, the peace of mind has been worth the extra cost of a fully isolated power supply.
