See one example below:
Problem: These are junk! Both bulbs have burned out within a two month period!! I cannot believe that this company can be in business with such poor quality. I have used infrared lights for my ball python for many years now and I get a varied range of months from a bulb, but I have never gone through two bulbs in a matter of two months! I am very disappointed.
Solution: 1
Explanation: The user seems very disappointed in the product. Because the bulb they ordered has been burned out earlier than usual. So, he gave 1 star to the review considering it extremely poor

Problem: It does track your heart rate, but the measurement seems a bit low (on mine at least). Works okay for telling if your heartrate increases or decreases so if you can match a reading with your target zone you can use it to maintain a target heartrate (though the exact bpm of your target heartrate might not be perfectly correct). It's got a pedometer too which works okay, and the app is kinda cool.
