Bryan from surf mode was great until I tried to return my purchase. He told me I could have until June 30 to try out surf mode and if I didn’t like it, return it for a refund. We could not get it to make a significant improvement on our 2008 Moomba Mobius LS so I returned the product. He received it on 5 July. I have sent him emails, text and voice mail, he is ghosting me. Very rude in my book. Just be careful because if things don’t go his way he seems to be disingenuous.
