So far my only complaint is the remote will not turn the unit on initially. Once I turn the unit on by pressing the button on the actual unit, the remote works great. The remote is rechargeable via the same cord for the unit, so give it a quick charge if you're noticing issues with it not working. Not a huge fan of the charging cable, but I don't hate it. Hopefully it has a longer life than typical micro USB, but makes it difficult to reliably charge it discreetly in the bag as you have to be careful the charger doesn't pull away from the unit.I find the size, fit, shape, everything, perfect. Relax and add lube and you will have no trouble getting it in or out, if you've use any similar product before. This is by far the most comfortable feeling product I've used. It's just big enough to stay put and give you a slight full feeling, however not at all large enough to make placing it or taking it out difficult.I find to get it in, on your side with knees up to your chest and letting the base sit (hinge) on your perenium and rocking it slowly in like a lever provides the perfect angle and position. I was surprised how easily it fit. Very well designed, and rigid but supple enough to make the whole experience more comfortable, particularly with insertion/removal.Definitely stays in place, but haven't tried walking around yet, however I'm fairly confident it would stay put. That said, it's not silent, not even super quiet, so keep that in mind if you like to wear this kind of thing out and about. Has not broken yet, but if it does I will update here, for sure.I find actually sitting on it to be far too intense and laying down to be kinda lacking, so finding the right position can sometimes be challenging, so be patient. This probably isn't unique to this product as every body is a bit different.
