Packaging was OK. the box was a little beat up when it arrived, i was afraid that the rails would be dinged or bent. The interior packing was very good and kept everything safe.
I would have given this product 5 stars if the assembly instructions were a lot more clear. They were terrible and it took way longer to assemble than needed. A link to a video would help or someone that actually speaks English (not a translator app) should write the directions.
The sled and rollers work very well. i did experience some binding while sliding the sled back and forth, that was more trial and error on my part.
*Important: I would recommend a bit extension when using this. I found that the bit supplied did not plunge low enough with my Dewalt router.
Overall: good product, would def recommend to the average DIYer

The sled works like a charm, it is extremely useful. I highly recommend it

Works perfectly. Very well built at a good price point definitely recommend.

After researching several options I went with this one due to the quality, reviews, and cost. It was fairly easy to assemble and worked great right away.

My first use was a new custom-built mahogany entry door with an interior profile too proud for door hardware installation. I simply set up the sled to run on the door styles and reduced the profile accordingly.
The top rail of the door was too short to accomplish the routing with the standard setup. I fabricated two pieces of 1/8" aluminum plate to cantilever the router base to extend the reach of the router by 6" to get the job done.
