The CaSino187 Compatible Roomba Module Replacement is a fantastic option for those in need of a new Roomba module. My analysis of this product showed that it is easy to install and works just as well as the original module. The quality is impressive and the price is reasonable. The only con is that it may not work with every model of Roomba but that is to be expected with any replacement part. Overall, I highly recommend this product for anyone with a compatible Roomba. .
