MM-350 MicroBrite Pro

Very nice little microscope. Magnification is good and picture quality is clear for this size. Easy to use with phone, fun to look small details. Also good for educational use, especially for kids or curiosity. Looks nice, very portable and light. Easy to carry and use anywhere. For the price it gives good value. Happy with it, easy 5 stars.

I really liked this microscope, and most importantly, my child absolutely loved it. At first, it can be a bit tricky to adjust the lenses properly so that a child can clearly see what they are supposed to see. Focusing the eyepiece/mirror also takes a little practice — but it is a microscope after all. Once they get the hang of it, it becomes truly fascinating. My child has been using it to examine insects, plants, bits of carpet, and all sorts of everyday objects. It’s a very educational toy, different from the usual ones, and great for encouraging curiosity and observation. A really nice way to introduce kids to science.

A very nice piece of equipment which is really just a mini microscope. I'd say it would be ideal for examining things under almost laboratory conditions, but that's not what I wanted it for. I thought it would be perfect for examining plants, insects etc on my rambles, but as it says in the description, the item to be examined must be placed directly under it, and should not be moving. I've had a lot of difficulty actually being able to use effectively outdoors. I thought it would be a bit easier to use than it is, and that's why I've only given it four stars. When I do manage to get it to focus correctly, the image is amazing. Problem is, that doesn't happen every time. I thought about returning it, but decided to hang onto it in the end. It wasn't too pricey, and maybe I just need to get better at using it.

As an amateur microscopist who has professional scopes costing £100’s, I was very sceptical of this device mainly due to its cost and “plastic” appearance. For the money at the time of this review I thought I’d give it a go as I wanted a really small self contained portable scope for general magnification whilst out and about and on my walks. When it arrived and unpackaged it my first impression was how small it appeared in size, yet it has a very solid feel to it. In holding it and operating the controls nothing creaks or cracks and the controls are very precise and positive. There are three main controls, a simple push click on/off button which controls the LED illumination which is very good, even and doesn’t appear to have any image hot spots. There is a sliding protruding arm at the top part of the scope which controls the zoom (always set at the minimum smallest x magnification to start viewing) and lower down a very deep long focus control which is again positive in action with good resistance and works very smoothly without notching. The scope doesn’t come with any accessories and my only criticism would be that a rubber eyepiece cap would be a nice touch to stop dirt, dust and scratching of the eyepiece lens at the top of the scope when in your pocked. I will fabricate something or find a small cotton reading glasses bag or something suitable. It runs on one AA battery to supply the LED light which is close to daylight balanced. The scope can sit on anything flat and a nice touch is that the plastic supporting fins on the base are wide enough to fit around a standard aluminium “well slide” for aquatic samples. I also experimented with producing a white screen on max brightness with my iPad Air 2 and placing a pre prepared microscope slide with a botanical specimen on the screen and then turning off the LED and mounting the scope onto the slide, this produces good direct through sample lighting and again I was amazed by the results. I also tried placing my phone (Motorola G22) over the eyepiece and taking a photo which wasn’t all that successful as it’s difficult to hold the scope still, get the right angle on the phone lens and press the phone shutter button without moving but with some patience it could produce some nice results. Those with 3d printers may well be able to design and print some kind of mount to get better results. I have no idea how many hours illumination the single AA battery provides but a good high power make should last many hours. The scope can be used without the LED light in good sunlight as the base support stand is clear and allows an amount of direct incident lighting through to the specimen. Overall an amazing very capable device and perfect for getting children interested in the micro world or indeed like me amateur microscopists who just want something light and portable to observe our natural world whilst out of the lab. The photo is copyright of NBS prepared slides (cotton stem xsection) taken with the scope set to 60x (its lowest magnification) using an iPad white screen on full illumination 100% as the under specimen lighting with the Carson MM300 scope mounted directly onto the glass slide. Camera was provided by Motorola G22 hand held over the MM300’s eyepiece.

I bought this to use with knife sharpening. It lets you see the very tip/edge of the knife and make sure it's sharp. It's OK, but the viewing sweet spot is very small so it's very tricky to use. The quality seems OK and I am confident that the published magnification figures are far more accurate than other similar products, so I don't regret it. But don't expect it to perform miracles!

The Carson MM-300 MicroBrite Plus is a fantastic little microscope for beginners, students, or hobbyists. It’s compact and portable, yet provides clear 60–120x magnification, and the built-in LED lights make viewing small objects easy in any lighting condition. It’s durable, easy to handle, and ideal for exploring coins, plants, insects, or other small items. A fun, educational, and practical tool – perfect for curious minds of all ages.

Although this’s a field microscope it has excellent magnification up to 120x & sharpness (easily see compound eyes of very small 10mm clothes moth and its body hairs haven’t used camera clip yet but looks sturdy I would imagine successful use would require determination but not beyond anyone

Really cool device, easy to take out, easy to use, stable, gives you a lot of fun.

Easy to use and provides clear vision.

This is an incredible little unit, very powerful magnification and clear image. LED is bright almost to the point of being too bright for viewing some more reflective surfaces. However, having used bulky tabletop microscopes that required slides with exceedingly poor lighting (weak light, even less effective mirror) in the past, this is a welcome change. Simply place it against the subject and view. Very simple and intuitive use of magnification and focus dials and on/off light button. Quality feel, robust materials, expect it to last for many years. The price is VERY reasonable. Bought one for both of my grade school aged children as Christmas stocking stuffer presents and they have had a great time examining any number of personal, household, and outdoor subjects. As a layperson I assumed the more powerful the magnification the better, however, for some subjects the magnification is almost too much and is a little disorienting for the viewer. Would probably have bought a less powerful magnification if I had of realized how powerful it would be. Overall very pleased with the delivery speed, the delivery packaging and condition, and the product itself. Excellent value.

Got it at 12 bucks. Very simple to use and it works. You can use your phone to amplify the view finder.

Requires some skill to use. Could be difficult for a small kid, if it's a bit difficult for an adult like me with no microscopic experience. Otherwise, it's great.
