Octopulse 4 about 2 years old. Works great. Was used with a wave engine so controller and power pack have about a month of use. Gave it a bath in citric acid and scrubbed the power cord on the pump to hard and outer cable got a tear about the 1/4 long. Let it dry out and double taped it with electric tape. Due to cord tear price is 170.00 shipped to cont US. Pump works as it should.
