This hand-held children's microscope works very well. It's easy to use. The overall structure looks solid, and it makes the hidden microbial world visible. Whether your child is interested in studying insects, plants, or other tiny objects, this microscope can provide an up-close and personal perspective that inspires curiosity and fosters scientific inquiry. Great value.

This hidden voice recorder is innovative and I do like this purchase. It is not just for work or school. You can use it to record anything, like practicing your speech for class or capturing memories like stories your grandparents tell. It's so easy to use; you just press a button, and it starts recording. Whether you're a student, a teacher, or just someone who loves to keep memories, this voice recorder is a perfect choice. It makes sure you don't miss out on anything important and helps you stay organized.

This bag has many many great features! It has a bunch of hidden pockets but only some of them are useful if your bag is close to full. It could use a waist strap as well. Looks awesome.

have always been fascinated by the hidden worlds that lie behind surfaces. With the K&F Concept endoscope camera for iPhone, I now have the opportunity to explore these worlds on my iOS device. This endoscope camera is specially designed for iPhones and iPads and offers impressive performance. The 7.9mm thin semi-rigid cable allows me to reach even the tightest spaces and corners that are inaccessible to the naked eye. The 5 meter long cable gives me enough scope to examine more distant areas. Whether it's inspecting clogged pipes, checking hidden electronics, or exploring other hard-to-reach areas, this endoscope camera opens up whole new possibilities for me. The camera's IP68 waterproof rating allows me to shoot even underwater. This is particularly useful when I want to check the condition of my pool, for example. The 8 LED lights provide excellent illumination, even in dark environments, so I can clearly see every detail. Connecting to my iPhone was incredibly easy. All I had to do was download the K&F Concept app, connect the camera and I could view live images and videos on my screen. The app also offers additional features such as saving recordings and sharing with others. A small note: This endoscope camera is only compatible with iOS devices, so please make sure you have an appropriate device to use it. Overall, I am absolutely thrilled with the K&F Concept endoscope camera for iPhone. It offers excellent image quality, easy operation and opens up completely new inspection possibilities for me. I recommend it to anyone who is curious about the hidden worlds behind surfaces.

On the outside, the backpack makes a nice impression. In my opinion it reflects the ravages of time. A beautiful dark blue with light brown leather applications, as well as buckles and zips made of a matt gold. The back is well padded and the carrying handles also have padding; ideal for longer journeys. An additional clip to close the backpack in front of the chest is also available. The top of the backpack can be opened using two buckles on the front (they are only visual, there is a magnetic clasp hidden here, but in my opinion it holds well and cannot be opened regardless). In this top cap there is a zip compartment in which a rain cover is hidden. The backpack can be further closed or opened using a drawstring to protect the inside from rain, for example.

I've always been fascinated by metal detectors and finding things hidden just below the surface. Vine showed me one, and yes please!

It's light, easy to pop the (included!) battery into, and a single push button to start it. No fancy settings, no learning curve, just battery, power, and go. I headed to the back yard, which is primarily sand thus easy to dig, to see what I could find.

Protip: Do not wear steel toed shoes for this activity, unless you'd like to find your own feet, again and again and again. Shoe change, and away we go.

Move the wand slowly over the ground to let it register. It will vibrate, make noise, and light up when it senses something, more of all three the closer or larger the object is. (For fun, I "found" a vehicle. Sounded like I hit the jackpot.)

My first score appears to be a child's porcelain coated iron toy pot lid that appears to have been buried for a while. It was about a foot down. As I dug, I kept checking the dirt I removed from the hole in case it was a smaller item hidden in a clump. Getting closer to my prize, it lit up all three lights and buzzed faster.

The next two finds are well-used, rusted out nails. They were closer to the surface, and the detector lit up easily to locate them. If I continue at this rate, I'll slowly build up enough scrap metal to upgrade my metal detector.

The kit includes a waterproof flashlight, which takes 3 AAA batteries, not included. It's a simple turn on and off at the base, and decently bright. There's also a storage bag for everything - the velvetish bag seems a poor choice for something used in water as it may not dry as well as a mesh bag would. There's a lanyard for the metal detector as well, but I did not use it.

This little gadget helped me find my gold wedding ring hidden in the grass. I had a pretty idea of where it was, but I couldn't see it until this detector sounded the alarm. And there it was.

I've cleaned my AirPods, especially the hidden spots that other things don't reach.
