no product after a month, April 24, 2011

This review is from: RADIATION DETECTOR DOSIMETER TERRA !!! ENGLISH VERSION !!!!

I made an order a month ago, because the company said it is in stock and should arrive within 2-3 days. After a month, I have not received it yet. The company sent me a strip of paper, basically saying "We do not have the product. We are not sure when that happens. Sorry." Now I am shocked to be asked the product review from Amazon. It seems that that stupid letter is treated as the completion of order.

This review is from: RADIATION DETECTOR DOSIMETER TERRA !!! ENGLISH VERSION !!!!

This is a first rate instrument with a complete English manual (including accuracy and calibration data. In particular the ability to switch between rate and Total Elapsed Dosage with out resetting the Dosage amount is a very useful feature as well as being able to program the audible thresholds.

The casing is high quality but it is still basic cell phone plastic so if you need a ruggedized enclosure you will need to look elsewhere.

This product might or might not be working. The manual was in Russian, so we really don't know if it is working properly. This was not clear when we purchased it.
