I find the quality of this product to be substantial in performance. The instructions given with the product does not explain the attachable magnet and hook. I learned about theses features via YouTube. I would add that being able to direct the camera with steering is necessary for many applications and one should consider having this feature for certain situations.

Love it, good quality pictures for price of device was able to find coolant build up and use photo for warranty work

Very happy with the quality AND the price.

It is as easy as turning it on . I used it to locate and extract a rock from inside my spark plug cylinder.

My husband is a mechanic and this is so small it gets in those tight places he said. It is a good item to get and great deal for the price.

It does well in small, dark spaces and has a great quality picture

Good picture, small scope easy to manipulate.

This endoscope is actually not comparable with the usual devices. The most obvious and biggest difference to other (cheaper) endoscopes is the movable camera (see video). If you actually want to look into a more complex cavity, this is just absolutely brilliant, no comparison to the normal devices.

I've been doing everything on my car myself for years, now I've gotten to the point where I can't get anywhere with my normal endoscope camera. It is incredibly helpful, especially when examining the cylinders.

I actually haven't found anything negative with the camera yet, everything is exactly as described on the product page:
- Large and really good display
- semi-rigid camera cable
- 10 meter cable length (so far always sufficient)
- reputable manufacturer
- SD card included
- Charging via USB-C
- Multilingual menu
- Very bright LED illumination
- Temperature sensor at the top
- Not dependent on cell phone or apps due to internal display
- Good camera

A big extra that is not mentioned in the description:
The device has WLAN. You can connect your smartphone super easy wirelessly (the app for the iPhone is called "AllScope"). The functions include, among other things, a live image transmission and that recordings can be viewed and saved directly without a PC on the cell phone (see screenshot).

Excellent product, worked well out of the box. I used it in a home HVAC product to figure out what ducts feed registers. I had to augment the camera cord with a electrical wire puller to give it some rigidity but other than that, it worked well. I bought 20 m camara cable. After using the 20 m cable I also bout 5 m and 10 m cable. Ken was very easy to work with when buying the 5 m and 10 m cable on a separate purchase

Great HD images. Use it for MX in my cars and planes. The pictures are from a Volvo engine. The Ralcam scope is very easy to use. Arrived with a charge that lasted about 30 minutes on/off.
