Hi! In this One-shot-video you can see Caterpillar Cat B10 - the most resistant smartphone on the market.
Because of standard IP67 you can use it in dusty enviroment or under the water.
In the package you will find accesories like this.
Small screwdiver for removing the back cover...
...to change two SIM cards or microSD card under the 2000 mAh battery.
microUSB port on the left side is deep and you need to use USB cabel from the package.
With a special button you can use flash light, but the light is on only while you are pressing the button.
The flash light works also when the phone is switched off.
On the right side is volume control and camera button.
It has only one function - turn on the camera app, nothing else.
Picture quality is really poor.
Three buttons under the screen can't turn on the display.
To unlock the B10 you need bare fingers...
...it is not possible to control the phone with gloves.
It would be better to turn on the display with three hardware keys instead of the power button on the upper side.
Next to the power button there is audio jack, but also really deep. You have to use the headset from the package, which is poor quality.
The screen is glossy and without automatic brightness.
The rollbar is poor without shortcuts.
Cat B10 is an expensive phone with average specifications.
But Cat B25 for 1/3 the price really impressed me! The same waterproof and dustproof solution, IP67, dual-SIM technology and only for 100 euros.
You can control this phone with gloves, writing messages is much easier, the flash light shines permanently...
FM radio works without headset!
Volume regulation is problematic, there is no volume button on the side of the phone.
The loudspeaker is nice and loud.
Specifications of the B25 is poor: no GPS, no Wi-Fi, of course. This is a simple resistant phone mainly for calls and messaging for around 100 euros.
Smartphone Cat B10 for around 300 euros is intended for users, who will use it outside for some calls, and when they come inside their office, earth-mover or bulldozer machine, there they can check e-mails with clean hands.
