When nothing else works, this is really helping...
The best thing about this kit is the sensorscope itself. It really allows to see the dust on the sensor. It has built in light and is easy to use, just put it on the lens mount and look. Also available in the package: a large number of swabs (made for crop sensors, but they can be used for large sensors as well; cleaning liquid, water based, no alcohol like the classical Eclipse solutions; a mini vacuum cleaner with battery pack (also USB kind of power supply) - this is probably the most useless gadget in the package. It doesn't really work (succion power is too low). Use a real vacuum cleaner instead (not in the camera, just hold the hose close to the camera (a few inches/10-20 cm away) and it will keep the air more or less clean while using the swabs or looking at the sensor.
Pros
- easy to spot the dust on the sensor
- large number of swabs
- nice carrying kit
Cons
- ridiculous price (this is just plastic and some stuff made in China - cost price is probably less than 10 USD)
- useless vacuum cleaner
