I came across this thread somehow and really wanted to give you an honest opinion from someone who owns the infinity 50G series. This tank is absolutely amazing and is a head turner everytime my friends and family come over. Don't listen to anyones lies here. I personally own this tank and have not one issue it's a bad butt tank, the build quality is flawless and tough. Check out my latest video on youtube and see for yourself
If you had a good experience that's wonderful and glad to hear they may have made some improvements. However, saying things like "don't listen to anyone's lies here" is totally uncalled for and just plain short sighted. Your experience alone does not serve as a tell all end all as you seem to think.
I was a cad lights / mode owner for many years. The build quality of my tank was undeniably poor in many regards. But worst of all, as MANY other people have experience as well with this company, is the extremely poor customer service. I had the exact same experience as @CavamaroZ28 when trying to order parts. If you place an order on their website they literally don't ship the items nor respond to any communications. This happened on several occasions until I finally gave up and moved on.
My experience with mode/cadlights was among the worst customer service experiences I've encountered in my entire life.
