Shipping times would be vastly different, given that I live in Israel

ReeFi is based in the US, so shipping times should be a lot quicker and a lot cheaper for you.
However, I've seen a post by Daniel (ReeFi's owner) saying that he flew to visit his parents in Taiwan for the new Chinese year, and new orders will be delayed - so that's something you need to take into account and advice you to reach out to him for more information, he's very friendly and will gladly answer your questions.
I do use ReeFi's myself, I've been using the 1st gen Uno (180W) over a 6ft tank for over a year and a half now, and more than satisfied with the results. I also have the new ReeFi Uno 2.0 Pro here waiting to lit a new frag tank I'm planning to setup soon.
