Depends what you mean by reliable? If you mean 20 year, Iwaki type reliability then nobody knows (though the answer is likely to be NO). The M1 and L1 have been out for more than 3 years. I've been running the M1 without any problems from the day it came out, so that is reasonable reliability to me. The L1 is the model that has had issues, mainly with overheating. The impeller/volute was redesigned about a year ago and seems to have mitigated the problems. The S1 hasn't been out long enough for any serious claims to reliability.
