I’ve always bought this brand. It has been tried and proven for more than 3 years. My partner phone was stuck between some sharpe metal and it pierced the face of the phone after retrieving the screen protector had a hole but it did not touch the phone glass. Best case ever.

Ex Output:
positive


Ex Input:
I’m very sad with the quality of this product, is the first time to try to print something. I was so frustrated and all was the filament. The printing look bad, like filled of bubbles and no definition. Is not the money is the frustration. I blame the printer, the calibration of the bed, the temperature. Again. Sad. Nothing else to say.

Ex Output:
negative
