Mouth of handpiece is a bit too small
I was rather surprised when I received the two handpieces to work with my Nouvea Contour machine that it did not accept my NC needles.  Expecially when it mentions in its advertisement it is an NC handpiece compatible with machine.  The mouth was just a wee too small to accept the needles properly.  When I contacted the seller he mentioned I must buy THEIR NEEDLES which is ludicrous, because they included two #1 needles with my pkg and when I tried the two needles they didi not go into the handpiece either.  Yet these were their own two needles.  I mentioned this to the seller but he did not address any of my concerns saying I must buy their needles.  I really do not like the inconvenience of wrapping back up, paying postage, waiting a couple more weeks etc.  So after thinking this thru tried appplying a lubricant to the bottom of the needles and they went in fine. BUT trying to remove them was no easy task, had to use a pliers.  So for 179.90 dollars I'll have to make do.  The handpiece works ok with the needles lubricated maybe if I apply more it will be easier to remove.  So unfortunately will have to give this  two star.  Two because the pens look nice and appear well-made.
