It has some really nice features like responsive grid, flexible layout system with flexbox support etc., which makes it very easy to use for front-end developers who are new in this field or even experienced ones as well! I personally love how cleanly organized everything looks (especially when using Sass). The documentation could be better though; there aren't many examples available online so you have no idea what exactly does each property do until after reading through all of them yourself - not something we're used too often at work but still an issue nonetheless since they don’t provide any sorta cheat sheet anywhere either :/.
