I have been a loyal Aquaguard fan for many years now and plan to be there but thought of wring a review on the Integra 7 model. This model is very good as far as water quality and built goes. The only drawback I have seen is with service. I had taken an AMC and not once has the service personal come to my place without me calling. Once the service guy comes, then thinks are smooth and they fix the issue very fast but getting them to come in the first place is the pain point. Poor service but great product...
