      These are absolutely fantastic binoculars and I'd give the same review if they cost double.

      7 Day Shop 10 x 25 DCF Binoculars I bought these the last time I ordered batteries from 7DayShop.com as I miss having a pair of binoculars when I'm out walking. I was impressed by the many reviews on the website and also by the guarantee that 7DayShop.com offer (if not completely satisfied you can send them back for a full refund). They cost £3.99 when I bought them and at the moment are on offer for £3.49 (including delivery). The binoculars themselves are very compact, folding up into the small case provided and quite easily slip into a pocket of my camera bag and, because of the weight, (175g) would not be too heavy in a coat pocket. The 10x magnification is excellent for the size and price. The optics are very sharp and give a fairly good colour range. The rubber body is excellent and protects them against any accidental drops (something I've done a few times). They have a central wheel for focusing and the right eye has a dioptre adjustment so that you can compensate for any differences between your eyes. I used these last year at a few air shows I attended and they were fantastic for spotting the aeroplanes in the distance. They were equally useful for when I go on nature walks with the children I take care of. They each have turns at using the binoculars and find it east to adjust them for their own eyesight. These binoculars are absolutely fantastic and I have recommended them to all my friends and to my Dad who was so impressed when he bought a pair that he has just bought some for his Grandsons (my nephews) who love going for nature walks. At the price they really can not be faulted and I would have paid more than double for binoculars of this standard.

      Advantages

      Disadvantages

      Despite the low price, these can't be recommended.

      The internet retailer, 7dayshop.com, is an unusual company. On the one hand, it supplies high quality, low priced items that because they are VAT exempt (if under £18), can be excellent value. On the other hand, they supply some kit that can only be described as tat. I often buy memory cards and batteries here, and have usually been happy with my purchases. Recently, I saw their 10x25 binoculars for sale at £4.99 and wondered whether they would be genuinely useful, or whether they'd fall into the 'tat' bracket. I wanted a small set of binoculars for my car glove compartment. As a birdwatcher, it's useful to have binoculars in the car at all times, just in case, but the thought of leaving my £300 Bausch and Lomb binoculars in the car did not appeal. The 10x25 designation means that the objective lenses (the big ones) have a diameter of 25 millimetres and the 10x refers to the 10 times magnification. I decided to try the 10x25's; after all, at £4.99, if they proved to be useless, I would not have wasted too much money. First impressions were good. The binoculars are small, lightweight, but of reasonable, solid construction with a rubberised coating over the lens housings. The binoculars fold laterally to quite a compact size. Fitting them to the face requires opening them up (they have quite a solid feel when being adjusted) to the required width to adjust to the wearer's eyes. Their small size means that they fit easily into the hand, and their light weight means that they would never feel heavy in use. The right hand side has a dioptre adjustment so that people with eyes of different prescription can have both sides focusing properly; an invaluable feature. Optically, they're quite reasonable. There's a small amount of chromatic aberration, where coloured fringes appear at edges of high contrast, but it's not too bad. They're not the sharpest binoculars that I've ever used, but they do show a lot of detail. So they're small, light weight, easy to use, sharp and show an acceptable quality image, but are they a good buy? Well, no. There are two problems that render these binoculars less than useful in the field. The first is due to the physics of the binoculars, rather than their construction. The 10x magnification is simply too strong for an objective lens diameter of 25mm. As the magnification of a lens increases, the brightness decreases, giving a dull image. For a magnification of 10x on a pair of binoculars, an objective lens diameter of 42mm or 50mm would be preferable. The image viewed through the 10x25 is simply too dark in all but bright sunlight to be acceptable. The second problem is either due to the design or a fault in my binoculars. When looking through both lenses, I found it impossible to get a combined image. There were always two separate images that never quite merged, causing eye strain after only a few minutes. This fault renders the binoculars unsuitable for sustained usage. One can look through a single lens, treating the 10x25's as a monocular, which then gives an acceptable, but dark image, but it's not ideal. Sadly, I was not impressed with the 7dayshop.com binoculars and have to rate them low, despite the amazingly low price of only £4.99. I cannot recommend these to anyone due to the faults I mentioned, which is a shame.
