    Easy to connect and disconnect. Even after connecting/disconnecting too many times it does not damage the wire and itself too! Made of high-quality aluminum. Don’t get rust easily!

    Easy to use and install! With the given instruction book you can easily install it. Really loved it. I thought that I need someone professional to install this. But fortunately, I have installed it by myself!

    A good Combiner even if a little tight when using large cables. Very nice looking. Also, well build ! Does the job.

    This box is expensive but does the job perfectly. Only problem is keeping the wires tightened to the breakers as it uses a traditional type of solid wire holder. You have to make sure it is in properly and all the way to the top and tighten and then tighten again and then wait awhile and tighten again. And never move the wires around as they could come out.
