The recently promoted Rocktrail, 30x60 Binoculars priced at £ 14.99 are, at first glance a cheap and powerful set of binoculars.

However the pair I purchased have been a major disappointment. The most serious flaw is that the two scope tubes are not aligned and the higher the magnification, the worse the error. At maximum magnification there is about a 1/4 frame vertical error between the two images. This renders them useless as binoculars at max magnification.

Light transmission is also poor and they would be unusable in low light conditions. Structurally they are reasonably well made and feel comfortable. The zoom function works and retains focus but the right-eye correction is minimal. There is no documentation supporting the "5 year warranty."

I may try to adjust them one day if I can be bothered.

Anyone buying one of these should test it at full magnification before making a purchase.

I would recommend paying more for a better product.
