Best described as "a nice little anime", with the focus on "little" due to episode length. The characters are pretty lovable, colorful and well thought out, but the lack of good comedy (and by that i mean stuff that actually make you laugh and not just smile or chuckle), story (and therefor its progression), relationships and romance as well as each episode being only a measly 7 minutes long kind of ruins it.
On top of it all there's more fanservice than the short episodes can or should be made to handle, but its mostly well placed so it doesn't stand out like a sore thumb as in some other titles. Best compared with "Seitokai Yakuindomo", this anime doesn't really hold its ground too well, still, its kind of fun and definitely worth a watch. 6.5/10
