This is a great looking faucet handle, but does not come with all the parts needed for full assembly.  It did come with all the parts listed in the item description, so this is entirely my fault for not being prepared.  My contractor did not have the extra parts (flow control valve etc.) to install, so we had to use a different brand.  I would definitely recommend this product to anyone with existing Moen hardware, or to anyone that has access to the necessary parts.
