Aside from a couple of issues, it's quite good. The biggest problem is when two of the girls in the harem cheat on the MC behind his back, which totally doesn't make sense considering their established personalities, not to mention it came out of nowhere without any prior hints. Was a bad move and disgusted a lot of readers. Even I, a generally chill person, had to stop reading for a few weeks just to stop feeling pissed off. There were a few other annoying things, too, but they are easier to overlook. All in all, it's worth the read so long as you're prepared to be angry at the author from time to time.
