Pretty terrible so far, being I paid over double of a fatmax and still haven't got them. After checking up with customer service, they told me it would be shipped that day, its been 4 days and still no shipping confirmation.

So after the bad review I left, I did receive the tapes. They feel a little cheap but time will tell if the wiper works. My problem now is that I paid for 30' tapes and got 25' tapes with 30' printed on the outside of the body. Looks like 25' blades got put into a "30' " body.
*EDIT 2
After posting anoth displeased review, mucktape sent me 2 new 30' tapes with the correct blades. I am happy to report that their customer service has been very good so far. Now to see how the tapes hold up...
