Amazon has the Fitbit Charge 4 on sale as a Limited Deal at $129.95.

CCC has this as the lowest price ever for anyone that has had their eye on one. Would pull the trigger on this if you have been meaning to get something with GPS in it so you can run without your phone.

Amazon product: Fitbit Charge 4 fitness and Activity Tracker with Built-In Gps, Heart Rate, Black, One Size
Customer Reviews:
This is my 3rd Fitbit (Charge, Charge 2, and now Charge 4). | Therefore, I already knew that the screen would be almost impossible to read in bright sunlight (an issue expressed by some first time purchasers/users). | I am very happy with the GPS tracking (I do turn it off when walking the dog, shopping, etc. to reduce battery drain, and only use the GPS for fitness walks, etc.). | I am very happy with the sleep tracking. | I am very happy with all the data analysis, presented in numerous graphs. | I did have one hickup the first night, as the blood oxygen variation graph was blank. This was corrected after a Firmware Update the on day 2, without me contacting customer support.
