Query: Poor Design- cause a lot of leak. Would have to buy separate parts!!

I saw the rating on amazon and it seem like a good buy to replace the old filter. When I started the installation, the faucet stem was to short which only allows the plastic stem nut to screw in but there was no space left to screw the plastic tube to connect to the faucet stem of the filter. I had to run several times to Home Depot and buy separate parts. After 6 hours later, I finally finished the installation. I turned on the water and water was just squirting everywhere. In addition, I also had to cut the spout nut shorter to make room on the faucet stem to connect the water tube line which involve me filing the spout nut. I was expecting a 20 to 40 minutes installation but it took me over 7 hours to finally get the job done. If I have know it would be like this, I would have bought a different product.
