I bought for my son the microscope. Can not share the opinion of the previous speaker. With us nothing wobbles. Pictures with the PC Kamara are perfect super sharp even at 40x. The fine focus requires a bit of tact / exercise is normal but we are talking about, after all, a fine instrument. For the price, I am very satisfied. PC Installation was quite simple. The light source could be a bit stronger. Color plates perfectly adequate. Locate the device for that price really reasonable.
