Best Upgrade For Existing K03 Owners
If you already own a K03, but want some of the best features of the new K4.
This height adjuster is the perfect upgrade. While I plan to purchase the new
K4 in the future. This is definitely the next best thing. The three levels of adjustment
make it very easy to get the exact angle. Down to very fine increments.
While the quality of the old height adjuster was very high. This definitely takes it to another level.
And customer service is some of the best that I have dealt with.
Every time I have had a question or issue. They have been there to assist me
and correct any problems I had.
If you are on the fence about getting this. I can tell you now that you will not regret it.
Unless you plan on getting the K4 pretty soon. This if the best upgrade you can get for K03.
