ONEVAN 16 Lines 4D Display Green Laser Level with Tripod

I set the level up to help me mark out the levels for the foundation of my extension and despite it saying it would be visible at a diameter of 20 metres I could barely see the laser at 5m, and also the button to set inside/outside and diagonal line doesn't change anything at all, very disappointed with it and will be bringing these issues up with the seller

Only just unpacked it , but it's easy to set up And quality is good

not used as yet but looking to use this week had it un packed and tested looks ideal for the price paid.
