Perfect as a personal item. NOT considered a carry on and you won't be charged for it! Wonderful when flying certain carriers that charge for everything!

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

Ex Input:
I liked that the price is good and that it seems to meet the same criteria as the other one though it does seem a little lighter. The main thing I like is that I cannot smell or taste chlorine. I have used this brand and model several times now.

Ex Output:
positive
