Simple to use.
The jig clamped securely to the door and made matching the holes a snap. The metal inserts make it feel more sturdy also. The hole saws were of good quality although having used them once I cannot speak to durability. I had to widen the hole for the knob as there was already a knob but no deadbolt on this door. The old hardware was smaller than new stuff so I had to solve that issue and using the smaller hole saw to line up the jig worked great. I was afraid that it would not work as well since I wouldn’t see the pilot hole and just had to go all the way through from one side. The saw and jig did great and I didn’t have a jagged exit on the other side. FWIW it was a wooden door. The only difficulty, and this is not unusual of this kind of hole saw, is that getting them off the adapter is tough. I hit the thing with penetrating oil and it helped but the adapter for larger one is pretty stuck. Fortunately that doesn’t keep you from getting the smaller one on the pilot drill and the smaller one is easier to remove. If you need to install door hardware, this kit is well worth it.

Does a decent job, at a good price
Does a decent job. Yes big $ ones will hold up longer but if you have a handful of doors this works great. Well thought out piece at a good price like most MIlescraft products.

Great tool and very well made
After decades of use my Knickset lock install kit wore out I wanted to replace it with a more compact unit and not plastic, most of the choices were either plastic or very expensive, since I don’t hang that many doors now I decided to go with this one and was not disappointed, it’s very well made easy to use even if you don’t hang a lot of doors. I was pleasantly surprised it seems to be a reasonable priced tool that should last a long time and the cost point was very good , if your looking for a door lock installation kit you won’t be dissatisfied, I work very well

Works perfect...
Used this for an interior finished pocket door, expensive door and a bit concerned about messing it up since it was all finish painted and just needed the handle installed. Well this item is perfect what a job it did!

Misses the mark (literally)
This jig leaves far too much power in the hands of the user-error gods. I’ve used the Milescraft mortising kit for several years and have always disliked the lack of alignment precision. I fixed that with some slight modifications to the removable plastic templates. For multiple doors, I have used the Milescraft jig with a flush trim bit to make a longer jig board which provides a precise, repeatable template for all three hinges on the jamb and door plus strike plate, left or right handed. This LockMate PLUS has a similar flaw in that there isn’t a good way to precisely and repeatedly hit your vertical alignment mark. You either sight it through the big 2-1/8” hole or the tiny hole to the right of that. At first I thought the tiny hole *was* for alignment…NOPE! It’s for assembly of the clamp screw. As soon as you add the red 2-3/8” spacer, the tiny hole is covered and can’t be used for alignment. Sure I can drill a hole through the spacer but…why didn’t Milescraft?? A diamond or triangular hole - visible through the jig body AND the spacer - would facilitate fast, repeatable vertical alignment. With the number of slabs I have to install, I need to make a vertical alignment jig. Cumulatively, it’ll still save me time but it’s frustrating to invest more time making an alignment jig for this jig, like the manufacturer and design team never actually used the product in the field on more than one door. Watch the product video - they really gloss over the “align the LockMate with your mark” part. And forget about making a reference line on the top or bottom of the jig because it was clearly CAD’d in metric units, so you’d have to add or subtract 42.5mm from your bore centerline. The materials are good, particularly the metal bearings, and the plastic seems sturdy with strong reinforcement ribs. Five stars for these, one star for accuracy and repeatability.

Great product.
Did the job. Easy to use. Really enjoy using this product. Seems to be built well. I really purchased this for 4 doors, and its still as good as new. The knobs and fit perfect and operated excellent. Definitely recommend if you're needing to cut door knobs.

Very helpful, doesn’t slip. Hole saws are fairly decent as well. I built 15 interior doors for my place. Did them all with this, saws are dull now but still a good investment.

works awesome no issues installing lock

The Lock Mate PLUS makes installing door locks quick and precise. The clamps hold well, and the included hole saws work for standard doors. My only minor issues were that the bits dulled faster on thicker doors and the clamp has a tiny bit of play, so careful alignment is needed. Overall, a great tool for DIY and pros alike.

great product, but i could not use it because a window built into the door did not allow for the clamp to be used. the manufacturer should take this into account in improving the design. otherwise i can see this as an excellent product for most doors.
