The set from Home Depot where the molding snaps into the clips.
The clips install easily with one scrww. The molding snaps in easily to the clips after a brief trial and error period.
The corner and end pieces work very well.
Biggest problem was where you would join two sections of molding. The system sells block pieces that go between the two 8 feet pieces. If you use these. no problem. But, we didn't like these blocks and just butted the two pieces together. Well, with the clips, we could't match them up perfectly. Solution was to leave the clips off about four feet and use adhesive to attach the molding.
I also shot brads into the bottom of the molding at some spots where I had gaps.
Caulking required in some spots.
Bottom line, I liked it after the learning curve and would use them again.
