AmScope SM-4BZ-FRL Professional Binocular Stereo Zoom Microscope, WH10x Eyepieces, 3.5X-90X Magnification, 0.7X-4.5X Zoom Objective, 8W Fluorescent Ring Light, Double-Arm Boom Stand, 110V-120V, Includes 0.5x and 2.0x Barlow Lenses

Having owned this 3.5 to 90X Am Scope for over 5 years, I am very pleased with it.I paid less than $300 for it and it is very similar to the $2000 microscope I purchased and used in my Circuit Card Repair shop in the Air Force.The dual arms make it much more stable than a single arm model and the base is heavy to prevent tipping.I use it in the 7X to 45X configuration (10X eyepieces with no .5X or 2X Barlow lens) which gives me a 6 inch working distance between the bottom of the lens and the table. This allows plenty of room for working with a soldering iron.The ring light is adequate, but I like to use a separate LED lamp to provide better depth perception. Having a goose-neck light would be ideal.Unlike fixed magnification microscopes, this one has a zoom which allows me to solder at a lower setting and then easily zoom in to inspect my work. It is also simple to focus.

The microscopes themselves are decent for what you pay.That said, the electronics are below average. I have multiple Amscope microscopes and I have had lights go out on two units. One unit I took the LED control box apart and desoldered/resoldered a cold solder joint on the PCBA.The other microscope has a bad potentiometer. It is probably a $3 part and I did the troubleshooting. The company doesnt want to simply send me a new part for a microscope that is 5 weeks old (I am going to repair it). After I have spent time going through and troubleshooting what is wrong, they have the nerve to ask me to pay shipping.Microscopes are pretty good for what you get. The electronics leave a lot to be desired and you are on your own if something goes wrong.

Product is great as was the service . I use this for many inspection applications . Not for Biological purposes that's a different unit . I would suggest getting the led light in stead of the florescent but that was my mistake . I would recommend this to any one wanting a quality professional scope . Its heavy duty I love it .

Excellent scope for the money. We've ordered several and will continue to.

It made my life easier to do all repair and inspection for smart phones and electronic boards.I recommend for repair and inspection.

nice
