All three toys run on batteries, which are included. Soft Tip requires one 1.5-volt N battery, G-Spot takes 2 AAA batteries, and Big Bang requires two AA batteries. My initial thought upon seeing these was that two of these types of batteries are not ones that I’d normally keep around the house, and that it’d be convenient if they all ran on the same kind of battery, but there isn't much I can do about that. The back of the box features diagrams that show you how to insert the batteries, in case you lose the small inserts that are included in the battery compartments. For easier reading, I’ll split my experiences with the three toys into separate sections with headers, as follows:
Soft Tip:
Soft Tip features a short, nubby cover that unscrews to open the battery compartment. My initial impression upon turning it on was that it packs a lot of power for a small toy. It is also fairly loud, perhaps comparable to a louder version of the vibration setting on my iPhone. The toy features three easy-to-use settings, each accessible with successive presses of the button. The first setting is a low, but still easily felt, vibration. The second is a slightly stronger, steady setting. The third is a rapidly pulsating pattern, i.e. “buzz-buzz-buzz-buzz”. Touching the button a fourth time resets the toy back to the first pattern. To turn the toy off, unscrew the cap. If the batteries are in correctly and the toy fails to turn on, make sure that the cap is on tightly enough.
My overall experience with Soft Tip was that it's not overly impressive, nor will it ever be the main attraction. However, it is a good toy for teasing or a quick session when you need just a little pinpoint stimulation on your clit to get off. The sensation reminded me of a firmer, vibrating version of a teasing tongue or fingertip. It did get me off, but at the same time, since I have enough other toys that are more powerful than this one, I did have a feeling of “is that it?” I did not notice much of a difference between the low and high settings, and neither one is particularly earth shattering. If the first setting isn't strong enough, then you’re basically out of luck. I prefer steady vibration patterns to pulsating ones, so the third vibration speed did not do much for me compared to the other two.
I haven’t tried it for this purpose yet, but my guess is also that Soft Tip would be a great toy to use during sex since it isn’t big or awkward enough to get in the way. Soft Tip probably wouldn’t offer much to more experienced toy users, but it’d be a great toy for beginners or couples who are just getting into toy play and think that this would work well for them. Advanced users will probably want to look elsewhere, since neither this toy, nor the kit as a whole, would likely thrill them.
G-Spot:
G-Spot features a simple ABS plastic cap that unscrews to reveal two AAA batteries side by side in their compartment. There is a thin circle of plastic-coated paper (?) that the manufacturer put in place to keep the toy from turning on while still in the packaging. My initial impression was that G-Spot’s vibrations are lower and more “rumbling” than Soft Tip’s buzz-y and higher-pitched ones. The first setting is a moderate, steady vibration. The second and third settings increase the intensity by noticeable amounts. The fourth is a rapidly pulsating pattern, while the fifth is a rumbling, roller coaster setting of alternating speed. If you like patterns, this toy offers basic ones. If you like power, the highest setting is moderately powerful and enough for me, but may not please those who need a lot.
In my opinion, the G-Spot is a decent toy for what it is. It’s not overly large, so it didn't require a great deal of warm-up in order to comfortably use, unlike many of the other toys that I own. It offers firmness and is relatively unyielding without being too uncomfortable, and does what it’s advertised as doing. It’s small enough to be suitable for a beginner, and the strongest setting could satisfy a moderate user. However, note that the controls can be a little bit fidgety and that over-screwing the cap can cause it to open back up – it needs to be on “just right” for the toy to turn on. This can be inconvenient. Also, aside from the limited vibration patterns, it doesn't really offer anything that a more experienced user wouldn't already have in his/her arsenal.
Big Bang:
Big Bang is a traditional vibrator with more girth than your typical beginner’s vibe. As is the case with G-Spot, the base of this toy unscrews to reveal a battery compartment covered with a insert to prevent the toy from turning on until the user wants it to. There is also another sheet inside the battery compartment that needs to be taken out. Once that is removed, a touch of the button turns the toy on. The controls here are essentially the same as those of the other two toys in this set.
The settings are similar to those of G-Spot: the first three settings feature steady vibrations of various intensities (low, medium, high). The fourth is a series of slower, pulsating, vibrations, and the fifth setting increases them to a quicker speed. The sixth is a mixture of slow, rolling vibrations. The seventh (and final) setting is a faster version of the sixth. Big Bang might be enough to satisfy intermediate users who enjoy traditional vibes with some power and a variety of patterns. The strongest setting (the third one) is intense compared to the other toys in this set, not to mention loud, so it may not be the best choice if you have roommates, kids, or otherwise a need to be discreet.
Big Bang does have its share of advantages when compared to other toys: it’s big enough to be felt during use, but small enough to be a warm-up for bigger toys; it also did the trick for me in terms of some very pleasant orgasms. The pluses of this toy are also similar to what I had to say about G-Spot: it's firm and unyielding, but isn't uncomfortable like some of the harder plastic toys that I've tried. If you like texture or a realistic feel, none of these three will likely be your cup of tea, but you likely would have already been able to tell this based on the pictures.
This isn't a "bad" toy by any stretch of the imagination, but, when push comes to shove, Big Bang is a basic vibe with few real bells and whistles aside from the patterns and slightly larger size. Therefore, advanced users are likely to already have vibrators with textures, girth, or realistic features that make this one seem boring. I’d recommend Big Bang for beginners who want to experiment with patterned vibrations and/or a little more girth, but more experienced users should look elsewhere.
