Muddy is pretty much crap from my experience. Ordered 3 and tried out 2. Didn't work. Muddy sent me 2 replacements after getting a ton of info from me. 1 new one worked, the original one I had not tried worked. The other new one failed right away with an "update failed" message. Muddy won't even answer emails on that one.
So, have 2 functioning cameras out of 5 (3 that I paid for).
