Mex,
I only run laptops and with MSW there were no visual artifacts. The power bricks did run hotter. Apple laptops do NOT play well with MSW, letting out the magic blue smoke.
My Cobra 2500 watt msw was a workhorse in my RV. I had zero problems with running fans or the microwave. It would run the roof air--but I decided that was perhaps unwise so it was only done as a test.
I moved to a hybrid inverter/charger because I thought I'd be getting voltage support. Unfortunately load support is NOT voltage support. That was solved with a Sola Basic autoformer. I do love the load support feature.
