This pump is genuinely amazing! I think this is my new favourite toy! The egg is really powerful and can be used alone first to warm up. Or, you can combine it with the pump for all-round stimulation. I found that the ears can get a little too buzzy after a while, but I think that is more of a me thing than the vibrator. It's got a huge battery life and charges up very quickly. The pump itself is pretty simple! I'd suggest adding a bit of lube around the outside for the best suction. Honestly not experienced anything quite like it before... Definitely a go-to toy now!
