Product review (3 stars): Good customer service.
After 20 days use the readout became faulty and useless. I tried removing the battery for a hard restart and it just got worse. I would return it but it isn't worth the effort.this us not a brand I would ever buy again...wish I could have given zero stars.

* Edited after contacting seller*

Although the unit was faulty the company did stand behind their product and offer a replacement or refund. Perhaps I just got a lemon and that happens
