Works as described.  Needed cold weather winter temperature monitoring in RV to prevent freezing over 200 feet away and through a metal building, no ordinary wireless thermometers would go that distance through a metal building.  The wifi receiver is set up in metal building approx. 100 feet away from RV and signal is strong enough to travel through metal building to go that distance then with wifi connection can monitor via website, app, text, etc.  Yes, occasionally the AcuRite server has hickups and goes down, but every company, Amazon, Target, Microsoft, etc. has server issues.. Such is life.
