Query: good value for the money

Others said this an that I dont have to say it again. . Because the manufacture did not lubricate correctly, you have to put some grease on the click, click part (where you go back and forward). When i tried it the first time, the 1/2 male, click part, it quit moving or hard to move. You'll to open the two crew and put some grease. After that, no problems.The reason of 4 stars.
