Great pricing. Can be nicely chain linked with another module in rows or stacked over each other. Proper planning is needed, software can be initially confusing but the Arduino libs are really well documented. Read the docs first if you get off chars or artifacts: I solved all issues with properly rechecked cabling and selecting propper hardware type! Very good quality overall. note: before hanging more then 2 modules to your MCU, make sure you got enough power/wattage otherwise your board won't be able to support the load, use external power for less headache
