I have been running a Rheem one for almost 5 years now and I haven't had a single issue with it. It's nice that it will keep the garage dehumidified. I also set mine to 140F and it does pretty well with multiple showers. We occasionally run out but that doesn't happen very often, maybe a handful of times per year. With rebates and installing it myself it was able to pay for itself in about 2.5 years.
