Product review (5 stars): Working well!
Electrical spikes and brown outs are a constant problem where I live and work in Latin America. These fluctuations have burned up our refigerator's compressor three times over the last eight years. After researching  various types of protectors, we choose the Exceline model.

After plugging the protector into the socket and the refirigerator's cord into the protector, the unit immediately went into the "waiting" cycle, as indicated by the yellow light. Approximately one minute late the indicator light turned green and power was supplied to the refrigerator.

The protector has been in service now for two weeks and it is working well. If the unit has experienced any spikes or brown outs, it has handled them automatically. We also installed one on a large deep freezer and it is performing very well also.

I plan to buy a third protector for a refrigerator in a separate location soon and would recommend this model to anyone looking to protect your large appliances from energy fluctuations.
