The customer support is great! They are always willing to help you out with any questions or concerns that arise throughout your project/s using their products / services. It's very easy to use when it comes time to taking measurements of all things needed during installation projects (which can be quite extensive). I have not noticed anything yet dislike about this product but would like more options in regards to adding other features such as color selection etc.. If price was an issue then we could purchase additional add-on items which do cost money however if one has enough knowledge there shouldnt really too much issues figuring everything themselves once installed & functional - maybe minor errors here nthere at times wen measuring something incorrectly due to lack luster understanding how certain functions work within program itself? Just make sure u know what ur doing before going into install process otherwise some mistakes may occur while installing materials together causing problems later down.
