Clear Sticker Quality Went Down

I often order stickers from Sticker Mule and love the feeling of their clear transparent matte vinyl stickers. After making some size changes to a previous design and ordered some sample stickers as a test - I noticed that half of the 10 stickers I receive had some lint trapped within the stickers, some printing smudges and/or a random mark in the clear vinyl. This makes me question the quality of their clear stickers if i ordered a larger batch. Unsure if I plan to order from them again.
