1. Look at the quality:

When purchasing a Shutter Window, first touch whether the blades of the Shutter Window are smooth and even, and see if each blade has burrs. Generally speaking, Shutter Window with good quality has better handling of blade details. Shutter Window blades made of plastic, wood blocks and bamboo chips will have a longer service life if the texture is better.

2. Look at the flatness and uniformity of the shutters:

Check whether the gaps between the leaves are consistent and whether there is discoloration, discoloration or obvious color difference between the leaves (check both sides carefully).

3. Look at the accessories adjustment lever:

The adjustment lever of the Shutter Window has two functions, one is to adjust the lift switch of the Shutter Window, and the other is to adjust the angle of the blade. When overhauling the adjustment lever, first hang the Shutter Window flat and try to pull it to see if the lift switch is smooth, and then roll the adjustment lever to see if the blade can be flipped flexibly and freely.
