Good size, wall looks nice, wish there were better capstones. I like the ridge to set back the layers, it helps the wall feel very sturdy compared to stones that don't have it. color variation is nice, adds a little interest without requiring extra effort during install.
These blocls are small attractive snd fsirly easy to install. This os the sevond project I've used these on but the blocks purchased in April of 2020 are different. and in my opinion, inferior to the same block purchased two years ago. While the size and color are the same, the mold was changed. The no longer have a groove in the back to guide cutting half block, and the main problem is the lip on the back is slightly radiused instead of straight. This means the interlock is bearing on two small points instead of the majority of the back edge. Secondly, if the offset of the secpnd course isn't exactly 50% the second course blocks will tend to be off square slightyl, which will be exaggerated on each suceeding course. Found out the hard way when I started my wall and shortly went into a radiused corner. Ended up having to cut several block to try to rectify the problem. I am pleased with the outcome, but it would have been easier with a straight back lip.
I would reccomend these as attractive and easy to use but would suggest to anyone to build the straight sections of your wall first. Photo shows older block on left with the straight lip and newer block with radiused lip.
