I must have about fifty of these on my layout, used exclusively in freight yards, passenger yards and industrial areas. Very easy to install and easy to use.

These are great for small layouts where you can reach each switch and don't want to spend a ton on motor switches. They are super easy to setup and use, the main assembly is already done, you just need to choose which hook to use and if you need the riser. These don't need to be super accurately placed, however it does help for smoother throws when positioned correctly. I have mine glued and nailed (Peco nails) to foamboard for my N Scale layout. They aren't very intrusive, however you do need at least 1 1/2 from the rail to fit the throw.

I have 5 turnouts on a small portable N scale layout. All of them being within reach, I replaced the remote controlled switch machines with these ground throws. They were so easy to install and what a firm, positive action!
