This is my second, first one lasted 10 years. Simply put, it's amazing. High definition display gives you all the information you will need or want. Is it to set up and works perfectly. Very detailed display and gives you many set up options. I love it.
This product is used on my boat and replaced a previous acurite unit that failed. The sensor head was identical which was great as it fit in the same holes. It was very quick to set up and worked as expected. The unit was very poorly packaged and it arrived with the top open and torn. It was also missing the lightning detector, but a replacement was promptly sent after I called. The display is bright and easily read, but not very intuitive. You have to switch screens to see outside and inside readings which is awkward and unlike the previous model. The manual is incomplete (I read every word) and the behavior of the display does not mirror it, especially for the rain reading. Sensor update speed is quite slow and it lacks battery backup on the display.
This is the third Iris 5-in-1 I've purchased. Two of the units were gifts to family members. We all are happy with the units. i have had to recalibrate a few times and I replaced a component damaged in a storm last year. I personally would prefer being able to speak to a customer service person when looking for information as opposed to online only contact.
