5 mm que te incluye favorablemente, pero es una pena que le falte eso, sería perfecto. Not sure I would be so interested at MSRP. THE SOUND QUALITY IS LOUSY. With all of the mission impossible style tactics that had to have been used to steal these from apple, I dont know how they are making a profit off of $199. And, so far, other than the Manufacturers sizing error, I have no complaints about these boots. The rendition of voice is beautiful. It is very nice for the price. 2 weeks later I had to contact them again. I received them on March 12, 2019. The wheels are very smooth and it is easy to push/pull the rack across the floor.
