I really like this toy, though it definitely takes some warming up to get it in. I have yet to take it all the way, but my partner finds it the perfect size and loves the stretch. The vibrating function is odd - you need to screw a metal part into the battery to complete the circuit I guess (Idk, year 10 science was a long time ago) but it is not a tight seal and any kind of movement can jiggle things out of place, either turning on or off the vibrations. You need to take out the battery to store it so that it doesn't vibrate non stop for hours (oops), but the storage case is very pretty and has a dedicated loop for the battery. One day I would like to invest in a nicer (preferably chargeable) vibrating sounding rod, but this one does the job and feels good. I don't know if it is worth the full price, but if you wait for it to get to 50% off like I did I think it's great.
