I have the Hummer, which looks to be the same shape. The cap that keeps the batteries in is a nightmare, but I love the deep buzz.
How are you using it? I love it as a clit vibe, didn't realize until rereading the page that the tip is supposed to be for g-spot stim. %-) That tip is so small I can see how positioning it usefully would be difficult. If it's uncomfortable internally, my suggestion is to use the humdinger's scoop against the labia and/or clit and another vibe for insertion. If it's uncomfortable externally, then use more lube and/or don't press so hard.
