Install was easy and it worked right out of the box. No changes to board dip switches needed.
Although its too soon to confirm long term reliability I can say the following.
Installation instructions were clear and correct
Installation was relatively easy and for the most part it fit right into my existing spa frame. No changes needed to the board config / settings (jumpers, dip switches) as it was correctly setup before it was shipped.
The heater tube was about 1" higher than the previous control pak (easypak 1204) so I had to raise the pump 1" from the frame floor platform but this wasn't terribly difficult.
The initial boot up and priming sequence was accompanied by updates on the topside display which was nice compared to the old easypak 1204 which was a bit cryptic in terms of understanding what it was doing.
The overall quality looks solid so I hope and expect it to last a long time.
