As no-one has said it yet I'll throw in the universal caveat of, every body is different so everyone can't like everything equally. Some toys will be 'orgasm guaranteed' for some people, but for others will be just 'meh' (or worse). So remember to read the reviews as well (both good and bad) and see if any of their descriptions chime with what you know or think you might like. 🙂👍
For what it's worth I think it's worth testing out every vibe shape. 🙂 Wands are good for broad stimulation (as opposed to precision, like a bullet), so they're not only good for people who like an 'all-over' feel, but can easily be shared by two people during (depending on position of course).
We like medium-large rechargeable wands like the Mantric and the Desire (and the squishy Tracey Cox one too now, though it feels a bit different because of the squish). We do have the LH mains-powered Classic and the Deluxe, but we find them a bit too industrial (too big, too loud, too heavy) for our bedroom style. For Mrs Chimp the frequency of the vibe seems to be as important as the power. She does like strong vibrations, but as long as they're rumbly (lower frequency) then the rechargeable ones are powerful enough. 👍
