The new iSclack is stronger than the older model. The two added diagonal‘s make isclack more un-flexible
to adapt the tool to the stronger touchpanel/frame adhesive of the latest models.
The increased rigidity permit to control much better the pressure applied to the touchscreen by the suctions.
Cracked screens can prevent the suction cups from properly adhering due to the air leakage through the screen.
