After my playing style had evolved towards using tremolo more and more, I realised I wasn't using my Epiphone Les Paul and ES-335 as much as the Gretsch, the Strat and the Duesenberg. After researching my options and because the factory tremolo on my Duesenberg Straplayer TV was so smooth, I decided to try their Les Term on the Les Paul. It was fantastic!
The installation is really easy and takes only 2-3 minutes plus the time it takes to remove and reinstall a set of strings. I think the engineering behind it is admirable both with respect to ease of installation and the fact that they can replicate much of the smooth action of their "real" full-size tremolos.
As the headline says, I went all-in and bought a second one for the ES-335.
Obviously, installing one of these does change the look of the guitar, and with classic icons like a 335 or a Les Paul you may or may not like it. For me, the usability was more important. I also find the Leas Paul to look less "altered" with this trem on while the 335 looks a bit odd.
