Excellent item!

The tube arrived fast, was very well packed and protected.
The included data sheets were very useful for getting it working.
It works well for detecting background radiation.
I also used it on a few test sources and it worked perfectly!

Worth the Wait

The tube was well packed and arrived in a reasonable amount of time given international shipping and customs. It works very well and initially, gives identical response to the CTC-5 that I am replacing.
