Great optics and reasonable price

After much research, we chose these because of past reviews and price. Although one of the first two didn't work, we reordered another set and sent original set back in as they were sold as a set. The video and camera work great! The optics are clear and we love the versatility. I would recommend this to anyone looking for a reasonably priced outdoor camera. I would even consider using this for a security camera since the optics are so good. I gave 4 stars due to trouble with the one camera but return was a breeze.

Very good quality for the price; the InstaFocus actually works well, and is a great addition to the product. Magnification and clarity are equal to other far more expensive optics that I own.

This monocular is a perfect match for my needs. Wonderful focusing range. Very close focusing up to and including viewing stars or more practically viewing birds, sports events, mountain peaks etc. Great eye relief for "with glasses or w/o glasses" with a simple "telescoping eye cup". Focusing is smooth and precise. Fit and finish is good. Any optical instrument is a compromise of something. e.g. I wish this monocular was half the size and came with a clip for my shirt pocket ! Not possible.
Carson Optical is a great company. The delivery was speedy and the product  quality is very good, not to mention at a very good price.

I bought this monocular to help sight in my rifle.  To focus and make adjustments is easy and the clarity is good for the price.  For my purpose it's well worth the money.

This guide scope is a bargain for the price. 60mm scope with a helical focuser that is firm and tight with a locking focus screw as well. I'm impressed with the function of the helical focuser as it is without slop in the mechanism.  Comes with the mounting rings with plastic tipped screws as not to mar the finish (which is flat black).  If the finish does get marred you just wipe it off,  I'll be using this for auto guiding with an Orion SSAG auto guider and it seems like it will work out well.  The rings and the "Vixen" mount will work well for my application.
Some people complain that the dovetail is NOT a Vixen style dovetail but it actually IS a Vixen type FINDER dovetail, There are two dovetails here in question: The standard Vixen telescope mounting dovetail onto THE mount  and the standard Vixen finderscope dovetail which is what this scope uses.  Great item for a reasonable price.

Quite clear optics for the budget price. Have installed on my Hatsan Striker Edge and it has been holding zero quite well so far. Turret clicks are matching 1/4 MOA as advertised. I'll may  get another one for another gun if this performs well after 2000 shots.

Excellent optics and well made.  The waterproof was a requirement and finding a quality brand for this price was excellent!

I'm very pleased with this lens given the price. Although it won't give a Canon L lens a run for its money, it's reasonable fast and has a nice range. The build quality is very good for this price point. Both the zoom movement and focusing are smooth. The zoom marking are well-marked. While the mount is plastic rather than metal, this keeps the lens weight down, which is always something that I appreciate. Despite being plastic the mount and housing are more than sturdy enough for even the most avid amateur photographer.

The image stabilization works very well and is an essential feature to have unless you have rock-steady hands.

I find the image quality to be excellent at all zoom ranges except for when it's at its max range, but even then it's more than acceptable.

It's certainly not the best lens that Canon makes, but I don't think there's another zoom out there that can match this performance at this price. It's a great second lens if you have a crop sensor body (such as the Rebel series) and the 18-55mm zoom (which is a common kit lens). The pair provides a wide range of shooting opportunities at a very reasonable cost. Highly recommend.

From all of my OCD research into alternatives to the EOTECH G33 that I really wanted, I found this to be the best bang for the buck magnifier for my needs.  I can't justify the added expense of the G33. I looked hard at the all the usual suspects and narrowed down my selection to the Primary Arms combo, Vortex, and the Burris.  The Vortex is nice, but the magnifier slides to the left and I'm right eye dominant, the Primary Arms combo was nice too, but the reviews were hit or miss. I like the quality material and workmanship, pairs up perfectly with EOTECH 512. A65, nice clarity, decent (could be better) eye relief. I highly recommend this, I like EOTECH, but I like keeping my money in my pocket.

If you are going birding or will be heavily using your optic I'd look for a better pair of binoculars, but if you need an inexpensive, small, and light optic to clip onto your belt and use occasionally, this will fit the bill. The view is surprisingly clear and bright for the size and especially the price. This isn't a toy, it's actually a decent optic.

It's also not 10x, but appears to be more like 6x after comparing against my other 10x, 8x, and 7x optics. This is actually a good thing, because holding a 10x monocular steady is difficult. This gives enough magnification to see what you're looking for without being too much and magnifying your hand shake.

Depth of focus is deep enough that you can set the focus and not have to mess with it much. It has a twist out lens cup so it can be used with or without glasses. The belt clip is handy to keep it attached to your belt or pack without having to use a strap. It has an removable front lens cap than can be easily flipped down while still being attached, or at this price you could just carry it an not worry too much about scratches.

I haven't used the Vortex monocular, but comparing against their binoculars, I doubt this is much different or worse than the Vortex 8x25 which costs 2.5x more. A Zeiss or high end will certainly beat this, but for occasional viewing this works.

Fits AR well with good clearance for BUIS. Reasonably light, better than average build quality. Good size and appearance. Optics not perfect but very good - but if you want perfect, cough up another $900. for a 'big name' scope. For my use, recreational shooting 100-200 yards (I'm no Marine sniper) it's a very nice, accurate, and affordable option with usable eye relief and good light collection from the 42mm objective.

Great optic for the price. I use it for many different things!

Ii bought this binocular because of my experience with other Swarovski optics. I needed a compact binocular but everything I looked at was just not bright enough or clear enough to bother with. After trying the compact Swarovski's I didn't hesitate to pay the rather hefty price these optics demand. The image seen through the Swarovski's is clear, sharp and bright. My only complaint is that they are made in 8x magnification. A 6x would be both adequate and appropriate for this size lens and would have been even brighter. You really can't hold steady enough with an 8x binocular to use the available magnification. I guess the bigger is better syndrome demands binoculars to be made in magnifications greater than is really useful. This is also true of my 8x50mm Swarovski binoculars as well, but the extra weight does help to dampen the unsteady image a bit more. Other than my personal feelings on magnification, I couldn't be happier with this product. I have an easy to carry high quality binocular in my pocket or butt pack when ever I go traveling, hiking or kayaking.

Better than I expected for this price.  Very clear optics, and focus adjustment knob is the right size and in the right place.  I'm very happy with this purchase.

I purchased this for a Meade Polaris 130mm EQ telescope.  I have only used it a couple of times but I like the clarity wide angle view and eye relief this lens provide.  Very good for locating points of interest, fine tuning the telescope then switching to higher magnification lenses.  Well worth the purchase price.

The 6 power by 16 mm lens combination provides a good balance between compact size, image magnification, and image brightness.  The optics are more than satisfactory for the price, providing almost non-existent color fringing and field distortion.  The carry pouch is adequate only, and I may go to a leather store for materials to custom-make my own case.

The monocular has a sliding focusing mechanism.  However, the adjustments are coarse, even with minor movement of the slider.  So it's tricky, but possible, to obtain a clear focus.  But when you do so, the image is very nice, considering the size of the optics.
