Bought one of these thru ebay, needless to say got held up in UK customs and I had to pay an extra £45.00. However item is extremely well made (though Chrome option would be nice!) and instruction are clear but in inches rather than millimetres which means it's important to re-check measurements at every step if your used to mm rather than ". I made up a mitre box as suggested which was invaluable, and a dummy tele body out of mdf for a trial run. When the day finally came to take a router to my guitar I was glad of the experience gained using the mdf body but fitting these things is not for the faint hearted so if in any doubt hand it to a guitar tech. Having said that if you've done the prep, it wasn't a lot of bother at all to fit and once the guitar was back together it worked perfectly. One thing I noted in the instructions is you don't seem to need the deeper rout in the cavity. Maybe this has been designed out by hipshot since the instruction were first printed.
Now I have to learn what to do with it but that's the fun I guess
i had one of these installed last year in a parts0caster, chandler body and warmoth gibson scale-brazilian rosewood-stainless steel neck, and i couldn't be happier with it. it always stays in tune, the adjustment for the travel is right on the back plate and chopped off a little weight from the guitar, to boot!! i'm probably gonna put another one into another more stock tele myself soon. the only issue i had was that the strap button is a little precariously designed, requires a specific thread size to attach and it did, i suspect only because the installation tolerances, score the body where it travels. no big deal, i wouldn't put one of these in a vintage tele anyway. first rate mechanism and highly recommended. if you want to, you can youtube search 'gary oleyar' and see the guitar played by the guy who installed it. nice cherry sunburst tele with duncan vintage hot stack in the bridge and a mini hum in the neck.
