In direct comparison to the C38 C60 is a little heavier (about 50g, at least in my models), due to the design but not the same stable. The focus is likely to be slightly higher and the footprint is slightly narrower. Tilts to both models at the same angle to the side and let go, the C60 kibbelt for a little longer, the C38 is for a back and forth firmly on the table. That makes the C60 course not useless, it is only the (small) demonstrate differences.
When C38 works recording the tape roll on a small drum that hangs loosely in two wells; the C60 the drum via a hinge to the dispenser is fixedly connected, the somewhat stubborn behaves when lifting it but not rocketing unintentionally.
Apart from that, they just have a different design that's it for now with differences. The rolling and Abreißleistung is (taking into account the fact that the blade of my C38 is a bit dull) I think the same for both. Is in my opinion also the exact same blade.
One must emphasize that both Abroller work really well and smoothly only with the in-house tape. The mitglieferte Scotch Magic can roll with one hand and tear. Other tapes (eg Tesa) have a slightly higher adhesion and va stretch more, which makes them not to pull off the blade with one hand. Here must be applied as back pressure in any case, a finger of the other hand.
Since I rarely use a dispenser, I'll keep the C60. Had I but known before how it behaves in detail, I probably would but again rather resorted to C38 because it is somehow more sympathetic to me.
The financial offer to the 4 included bands is of course good.
