    Double Eye Jewelry Watch Repair Magnifier Loupe Glasses With LED Light 8 Lens US
    16. Okt 2018
    Unusable
    An item is good only if could be used for the purpose it supposed to serve. Those magnifiers cannot focus unless the lens is just a few millimeters away (about 5mm) from the object, otherwise nothing could be seen. For all practical purposes are useless.

    100V-380V High Voltage Power Supply Kit 12V 6V F Magic Eye / Nixie tube filament
    23. Jun 2019
    Be careful how to use it, or will explode.
    This product is just an AC to DC rectifier with some voltage regulators. It has two AC inputs and two DC outputs (as separate channels low voltage and high voltage). As is described it gives the impression that one channel could boost the 120V AC input to a higher DC voltage but this is not the case. What you get is just whatever AC input rectified to DC with a voltage regulator after the rectification. That is OK for some applications. However there is a dangerous condition because the high voltage DC output is NOT ISOLATED from the AC input and there is the dangerous condition that someone may connect the AC live (via the rectifier) to a ground on the DC side and this will result to a big BANG. So, be careful where is used (use an isolation transformer). I am not going to use this for anything but the components from this product I could use in another project so the money I paid are not completely lost. Finally I do not think that this has been designed by an experienced professional. The right design would use a PWM converter/regulator with a small isolation transformer.
    Excell Pentax F 35-80mm F4-5.6 SMC Lens 35-80/4-5.6

    Pentax F35-80mm F4-5.6
    This is the second F35-80mm I have, one is fitted to my Pentax K3 (DSLR with 24MP APS-C CMOS) having an effective focal length 50-120mm. The other one is fitted to my film camera Pentax MX (35mm). For the money (about $35) The lens has excellent performance, it is quite sharp with good contrast, of course at the F5.6 you need either a bright day or a flash.(usually I do not go greater than 200ISO). With the 35mm format this is a very good 'standard' zoom lens. This is a low cost lens but overall a very nice lens for the money, for anything better probably will cost 100's of $. I do not find any serious drawbacks, the lens has auto focus (screw type) and auto-exposure (F stops) and work very well.
