Tensioning is somewhat difficult - probably. I'm a bit of oil to the corresponding screw thread mount - and a few hairs have a slightly lower voltage.
Overall, however, a solid bow hair with wider contact surface ...

For this low price definitely a recommendation - for comparable arches you pay significantly more often ...
