This 3x Barlow is an OK value for the money. I would have liked to have had a clamp ring feature instead of just a setscrew to prevent misalignment of the eyepiece, but what can you expect for the price? I would recommend this product for those willing to accept the compromises.
This is a high quality barlow lense. When used with your telescope and normal eyepiece you get a trippling of magnification. Most useful for EP's 24mm and larger. A 30mm EP becomes a 10mm with use of the barlow. The look and feel of the barlow are both high quality. Make sure you have a sturdy mount for the scope, owing to the increased weight.
