The Compact mini G is more rumbly than buzzy, which some may find very pleasant. The vibrations are rather deep in feeling and they're spread out through the vibe. The vibrations are mostly located in the head, and it can be used for some pin-point stimulation due to the "G" tip. The material of the compact G has no give at all though, so it can be uncomfortable for some. When I use this toy I find that it vibrates so strongly that the stiffness of the plastic is irritating on my clit. That may just be me though, so experiences may vary.
Something to take note of: This toy has a battery caddy sort of style to it. When inserting this back into the toy you have to insert it the correct way, also the metal strip should align with one of the metal strips in the toy. It's not hard to figure out but I've included pictures of how it looks inserted that might explain better just in case.

-Words on the button-
The power button of this toy is printed with the words Low, High, and Off on the bottom for unknown reasons. It could possibly make one think it's a turn dial, but this vibe uses a push button operation. The controls are very easy to use. You press the button once to turn it on, and you have to cycle through al the settings to turn it off again. There is no easy off switch, so if you get walked in on a lot then this toy won't help you. This toy has 5 functions: 3 speeds of vibration and 2 patterns of vibration.
1. Low vibration
2. Medium
3. High
4. High pulses
5. 3 escalating pulses (A low pulse, a medium pulse, then a high pulse)
My favorites are the medium, high, and high pulse functions. I don't really have a pattern or vibration I don't like, for the vibrations are all pretty good and strong. Though admittedly I would prefer if the patterns weren't the last two functions. They do feel a bit weak in comparison to other settings if you've been using the High vibration setting for a while. The patterns can also be more of a tease for some, so I think they'd be best to start out with.
This toy can be used vaginally, but I don't think that it's very effective for this. The vibrations are more rumbly than buzzy, so it is pleasant to just feel inside. It's pretty terrible for thrusting in my opinion though. It has a lot of drag to it, and it's also very hard and rigid. There is also the matter of the strange ridges this toy has on it which make it harder to clean. The ridges are a bit deep, so they can hold onto a lot of fluid. If you are absolutely intent on using it internally, I recommend purchasing a cheap toothbrush. When cleaning toys with deep ridges or texturing you can use a tooth brush to get in close to clean any deep mess. No matter how you use it, it's always good to check that there aren't any fluids hiding in the ridges.
As I stated before, the compact g is pretty noisy at times. If you keep a firm hold on it the sound is dampened a little, but it's still a bit loud. Though it's also water-proof, so if you lack privacy you can take it with you into the shower. The battery compartment does have an o-ring to keep water out of the battery compartment, but only if you twist it on properly. Sadly I had a bit of trouble with twisting on the top to the battery compartment. If you twist it on too tightly it can end up making a popping noise, but it's not supposed to do this. This noise indicates that you've twisted it too far and you'll have to twist it on again. If you don't grip it too harshly when twisting the cap on it shouldn't do this, but I get pretty aggressive with twisting on battery compartments. Most of my toys are waterproof, but I don't want to ruin them just because I didn't seal them well enough.
