The 210-RLED Cordless Microscope from National Optical is a three-objective single viewing microscope with a 45� inclined monocular. The three objectives are 4x, 10x, and 40xR, and feature achromatic lenses which reduce color distortions introduced by imperfections in optical elements. Reducing these color distortions allows you to see sharper images with better color fidelity. The retractable 40xR objective has a spring-loaded lens which will retract when it touches the slide thereby protecting the lens and the slide. The parfocalled and parcentered design allows for switching objectives without having to realign your sample and without losing focus. Both the turret and the included objectives adhere to the DIN microscope objective standard. This means that you can use any DIN objective with your microscope worrying about it ever becoming obsolete. The focusing system performs fine and coarse adjustments. The turret has four holes and can accommodate a fourth objective.

To see details of your specimens more easily, the microscope has an LED illumination system with adjustable brightness. The light intensity it delivers is equivalent to that of a 20W incandescent bulb. The white light from the bottom LED emitter is focused on the sample with a 0.65 NA Abbe condenser. The iris diaphragm located underneath the stage allows you to tune the contrast of your images while using different magnifying powers.

The microscope also features a 5.3 x 5.3" platform with an adjustable height and has two clips which hold your slides securely in place. The frame of the microscope is made of cast metal with gray enamel finish.

Included with the microscope are three rechargeable AA NiMH batteries, a wall adapter, a dustcover, and two Allen wrenches for rack stop and eyepiece socket tension adjustment. To recharge your microscope's batteries, just connect the microscope to the wall power adapter.

Absolute game changer for chronically dry feet/cracked heels
Size: S (up to size 7)-Beige
I had recently bought a pair of silicone heel/ankle wraps to fill out my boot a little since I noticed my heels were lifting when I was skating. I tested them out around the house and noticed they left my heels softer while the rest of my sockless feet got quite dry. So I got these full foot silicone socks to see the effect of having my whole foot covered. I slather the entirety of my feet with Dr. Scholl's Severe Cracked Heel Restoring Balm (love how convenient it is to apply it to my feet with the solid stick form) and then slip them into these silicone socks. After just a couple hours, when I pull out my feet they're (a teeny bit sweaty at first), but then overall soft and smooth and have absorbed the balm fully leaving barely any residue in the silicone sock. I find these silicone socks generally comfortable; I wear them in the evenings while relaxing on the couch, take them off after a couple hours and let my feet breathe a bit, and then reapply my balm and socks and wear them to bed. If I wake up in the middle of the night, which I almost always do (not because of the socks), I'll take the socks off and allow my feet to breathe again. I wear a woman's size 6 shoe and the small size is pretty comfortable. However, I made the mistake of wearing them while being on my feet for a couple hours straight during household chores -- they must've somehow cut off my circulation a bit with the standing, so I wouldn't recommend wearing these silicone socks while being active. And since they're not exactly my foot size, they slide around sometimes and will start to feel tight at my big toe. But if that happens, I just tug on the toe area of the sock to give my big toe more wiggle room and problem solved. Prior to wearing these socks, I was soaking and doing heavy duty exfoliation of my feet every week. These socks seem like they'll work to help me extend the time between soakings and exfoliations. The 5 pack is a great value. So far none have torn, so they seem rather durable. Not sure what I could even do to tear a hole in these.

EXCELLENT FEET MOISTURE PROTECTION
Size: S (up to size 7)-Beige, Size: S (up to size 7)-Beige
Why did you pick this product vs others?: I have burns on my feet and needed something that I could put burn creme on and still walk around in with. I tried other silicone footsie but they would teae really easily. So far these are doing really well for this purpose. They are holding their shape too. The only caution I have is the same with all silicone footsies: They can be slippery on wet floors, so also wear with socks over them. The biggest issues is when they say a size they mean it. The silicone used in these have little give in them, so they won't stretch out and loose their shape. That can be a good thing, or not so good, depending on how well they fit your feet and what your intent is with wearing these. The other issue is if they fit snug around those toes, that tends to be where the first tear in the material will happen. Because of how these are made, the tear is actually more like cracking in the material and once it occurs you won't be able to get much use out of the sock after that. If you are planning to wear them around the house or for long term use, I suggest going up a size or look for the toeless options.

Silicone socks
Size: M (up to size 9)-Beige
The socks are sized large. The quality of the silicone is good. But they slide around on your feet if you try to walk, making them difficult to use and a bit uncomfortable. Unless you are able to sit for long periods of time the likely will not work well. Recommend looking for a better value.

Fantastic. I put lotion on my feet & wear them when I go to sleep. I often wake up during the night and will remove them to find my feet soft and smooth. They are strong and fit my size 10 womens’ size.
