I have the previous Inkbird wireless. When it's working it is very good, and easy to use. Most of the time I had to charge it a day before using, and half of the time it would not work with their App. I recently got the Tempspike, which on the model I have, has it's own base, no app needed. But you carry the small base with you constant updating. It worked right out of the box, and has been perfect over 8 cooks. This one also has a signal extender which I definitely need. Has signal throughout the house and yard.
