Starting with the good points. The door units are solid, well constructed and have a nice smooth finish. Mine are nicely grained and arrived unblemished. Take note, however, if you pick these doors up rather than having them delivered to your door, you have to have a way to get them to their destination in a vertical position...and the package is over 7 feet tall by 34" x 20". According to the personnel at Home Depot, the boxes are not to be laid on their sides and they are marked as such. So it takes some creative tie-downs just to get these doors home...and I wouldn't want to risk it on a windy day. After unpacking them, I'm fairly certain they could be laid down if you take reasonable care. There was one loose package of hardware inside that was not secured and could just fly around within the cabinets which could possibly cause damage to the oak surfaces. Other than that, if you handle the package carefully you should be able to lay it down flat on a trailer or in a pickup bed.
And the not so good. Building the jamb was a horrific experience. The screws are very soft, cheap metal...and you are screwing into oak...so the results can be disastrous. Even after drilling pilot holes for all my screws two of the heads snapped right off and a number of the phillips heads slots simply stripped out as the screws were being driven. Why Murphy Door would go to the effort to make such a nice piece of wood furniture and then expect it to be put together with inferior hardware is beyond me.
There is also one major design flaw. If you want to mount the doors as "in-swing" then four of the the pilot holes for screwing together the door jambs are in a direct line with the screws used to mount the hinges. This is just plain poor engineering. This means one screw in each of the hinge plates must be left out in order to screw together the jambs.
I found the directions quite difficult to understand and far from easy to follow...and I'm not a novice builder. One problem is that the directions are in three different places. There are two separate manuals which come in the box, each giving a portion of the necessary information and then a third manual on line specifically for french door units which provides some of the other information needed to understand the assembly. There is also an app you can download to your ISO or Android device which claims to be a "easy step-by-step interactive 3D instructions. It's free. But I found it less than helpful. It is sort of like an animation. But the crude drawings and the darkness of the images makes it nearly impossible to see what they are trying to show. It might be helpful to you...wasn't for me.
Bottom line. The doors themselves are nice quality wood and well constructed. But the portions of the "kit" which the purchaser is expected to complete have inferior hardware, marginal directions and some design flaws for screw placements. I ended up constructing the jambs pretty much using my own knowledge and some much higher quality hardware.
I would rate this installation as NOT for beginners and something of a challenge even for the well experienced. The results can be very nice...but it take some effort and some frustration.
