Bests & Worsts Reviews from Amazon

The thermal color changing works well and does not appear to be degraded after being exposed to printer hotend temps. In the past few months I have had only one nozzle clog while using Hatchbox and Amazon filament. In the first two days I have had 4+ clogs in addition to surface globs and some areas that look like they melted (further observation indicates that viscosity for a given temperature is not consistent). Playing with the bed and hotend temps helped very little; at the cooler end the material was very rubbery but would not adhere to the bed or itself very well and at the hotter end it would sometimes flow out like a watery liquid. Also noticed that at room temperature the filament on the spool was a lot more brittle than any of the other PLAs I have. The color changing effect is quick and quite noticeable but just be prepared for a lot of fine-tuning and aborted prints. Edit: changed from 2 to 1 star. 5 more prints and every one of them failed due to clogging. Tried even higher temps, slower print speeds, and a new nozzle with no luck. Switched to Hatchbox PLA black @210c and 120mm/s and popped out a perfect 3D Benchy on the first try.
