Mostly solid, minor tweaks needed
This PHP chat application is pretty good overall. The AJAX integration makes for a smooth, responsive experience, and the Bootstrap styling is clean and modern. Setting it up was straightforward enough, though the instructions could benefit from a few more screenshots. I did encounter one minor bug where messages sometimes wouldn't display correctly if the user refreshed the page, but a quick code tweak fixed that. For the price, it's a solid product that does what it promises. A few minor improvements to the documentation would make it even better.
