Query: Two defective units

Bought one around Thanksgiving that broke after 3 weeks. Honeywell customer service said the circuit breaker fuse blew and to return it. Replaced the first unit and the same thing happened after another three weeks. Worked great while they lasted - added much needed humidity to the air, mild gurgling noise of the boiling water was very relaxing, and cleaning, although time consuming, was straightforward.
