Radian eyepieces are well respected for their planetary/lunar performance and I've found that to be superb, indeed. However, the 8mm Radian has also become my go-to eyepiece for globular and open clusters. Focusing is extraordinary, with images snapping into focus easier than any eyepiece I've used before.
Pros: Superb mid-power eyepiece, tack sharp in fast scopes
Cons: "Instadjust" takes time to get used to (but it does work)....
Would recommend: Yes
