Glad I did research and we spent a little more to get the features we wanted.  Love, love, love the MagnaTite Docking, ShieldSpray Technology, SpotShield Technology. 
Knew I wanted a magnetic docking faucet, as shopping around at home improvement stores showed plenty of droopy spray wands hanging down, but magnetic ones were secured. 
ShieldSpray is like a power wash for dishes; we just have to be careful of setting the water force/pressure. 
SpotShield on faucet and escutcheon (deck plate) is great because we have very hard water; just wipe off any water splashes.   Even my husband who teased me about the features I wanted has come to praise them.  
Once we could remove the old faucet, my husband easily installed the Spargo.  
It is very tall, which was a concern because the window is just a few inches above sink.  We quickly got used to the new profile and we currently have no complaints after two months of very pleased use.
