Lelo are great, but they aren't perfect, and honestly, sh!t happens.
I burnt out a smart wand's motor in about three months due to epic masturbation, and now my partner's is going the same way, but his is much older.
I'm not saying it's your fault, but just to consider how much you use it, because they aren't invincible :P
But yeah, every few months there's a thread on here about poorly Lelo toys. It's not a super common thing but it does happen, and at least there's a warranty in place so you can get some recompense.
It's not great, especially if you got yur original before the price hike (which from the age, you did) but you honestly have to try and make the best of it. Keep your eye out for offers in their emails, as they are decent.
