Strapless dildo

Has anyone tried this type of strapless dildo? I'm curious to know if it actually stays in place during use or if it tends to move around too much. Would you recommend it over a traditional harness? Also, does the vibration feel strong on both ends or just on one? Any experiences or advice would be greatly appreciated!
