I installed it very easily with no tools. Since it has washers at the connections, Teflon tape was not necessary. I was very pleased with how easy it is to control the settings on the hand shower. My previous hand shower had a difficult sliding valve that was nearly impossible to operate with one hand, especially a soapy hand. The shower and shower head both can be adjusted up or down, Left or right easily due to it's lightweight. The head and wand operate independently of each other and the wand offers four spray settings. I sometimes have to remove the water restrictor washer out of some cheap shower heads but that was not necessary on this model, there's plenty of water flow. Although it's made up of plastic, it feels solid and works very well. the hand shower has 4 spray settings and has good pressure.
