Although these binoculars were very cheap, I took a gamble on them because Helios are a good manufacturer of other quality bins. To my great surprise the 3D effect of porro prism binoculars is very good and the magnification of objects in the far distance good. Light, robust and comfortable, suitable for spectacle wearers too.
If you want an inexpensive pair of binoculars for every day or work use, these do the job well. Obviously one can pay far more for better image quality - but do you need to?
