Being my first anal vibe (and my first truly anal toy) I wasn't quite sure what to expect, but even with that I'm very pleased with this toy. The one thing I have to mention right up front, however, is that I haven't used this a whole lot for anal. Mostly, I just haven't figured out what works for me during anal play, so I've mostly been using it as a clit/vag vibe.

That said!

Pros:
Size-Very non intimidating in both girth and length for anal beginners, and (at least for me) very easy to insert/remove, and felt filling without being overwhelming.
Vibration-This toy has several vibration settings, and for me the highest is quite strong; I can easily see it being too strong for some, but since it has a sliding wheel to adjust the vibes you could easily find one that works for you.
Easy off-Just slide the wheel completely to low and it's off.
Battery compartment-Very easy to put the batteries in and take them out.
Material-Made of silicone, so it's easy to clean and body safe.
Noise-VERY quiet (although it might be a bit loud for a shared space when on the highest setting)
Also makes a very nice clit/all around vibe.

Cons:
The color-Very small con, but it's a much brighter pink than it appears on the site, which could be a turn off for some people.
Vibration-It's much more 'buzzy' than 'thobby', and while that works for me I can see why it wouldn't for others.
Not waterproof.
It would be very easy for someone finding it to know what it is.
The flared part has some nubs which I suppose are meant to be stimulating to the perineum etc., but I didn't get anything from them--obviously your mileage may vary on that.
Definitely not for size queens.

Having played around with this vibe a bit more:

-I would probably rate the vibes a bit weaker (maybe a 3.5), though that may be because my batteries are dying.
-Similarly, I'd rank the noise higher--I usually play with music on so am not always aware of the noise. I'm not sure if this is also due to the batteries dying or if it's just the way the toy was originally, but when used externally I'd probably say the 'Bee' is a 3 or 4--although when used internally as it's intended, you can barely hear it.
-While I think it is a good warm up anal toy, my main problem (and the reason I mainly use it as a clit vibe, still) is that for me, I can't really feel the vibrations when used internally. This could differ for others, but if you know you need strong internal vibes, this toy may not be for everyone.

All this aside, I do still like this toy. It is a very good beginner's buttplug and also doubles as a good clit vibe, so for now it keeps its place in my toybox.

*Also, something that was brought to my attention and something that should be kept in mind is that this toy is actual made with TPR silicone, not pure silicone as I had previously written.
