4 faulty Twisps in a row - I'm giving up on Twisp

I'm now on my fourth Twisp Clearo because the last three have all failed for various reasons. Today this one stopped charging and the battery is getting very hot even when not in use. I'm told this could be very dangerous so I have stopped using it. I am now fed up with trying to get a product that actually works as it should - which Twisp clearly does not!<br> <br> I am amazed that a product manufactured to such low standards is still selling... Or am I just unbelievably unlucky?<br> <br>
