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.
I got the telescope a few weeks ago. Loved it so much I had to get these to make it even better and I'm amazed how much you can really see with these and how amazing everything looks with them. If you think you want it...you do.
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.
