- (March 17, 2005) We have done some testing and we like your software. It is very fast and very repeatable.

- (November 16, 2004) I did some measurements for collegues of other departments and I think some of them will soon contact you to get their own licences... In my opinion you did a great job programming this handy peace of code!
- (September 2, 2004) I´m very happy with the software. During the next couple of weeks I´m going to summarize the results for publishing, if you are interested I´m going to send you a copy.
- (May 24, 2004) Cheers for the quick answer, you´ll get an A++ for customer service ;-) I got the fax and talked to my boss already, the quote is accepted. As soon as I get my equipment I´ll send you a short statement about setting up the software and about the results of my first measurements. Have a nice week.

- (November 16, 2004) I just finished writing my PhD thesis and also included data obtained by BuzzoSonic there. Great thing!
(May 12, 2004) Yes, in fact it's [Buzz-o-sonic] working very well. Christian is a colleague working at another institute of our department and always went to us for the measurements. That's why I gave him your address.We are all very satisfied with your software.
- (February 5, 2004) Actually, we find the software very useful and already used some results for a publication in the Cocoa Beach conference proceedings. I attach the file, you may have a look at it.
- (January 12, 2004) We think about writing a paper dealing with the mechanical properties of porous ceramics made from different techniques (foams or fibrillar structures). For that we will use BuzzoSonic first.

(October 25, 2004) We are pleased with the software and the fine support you have provided to our staff. I appreciate good technical support, which is missing in many companies these days

- (August 10, 2004) It [Buzz-o-sonic] is working well. I haven't been using it for the past couple months, due to some reassigning of work loads on my behalf, but up until then it has been wonderful and apparently is still working well for another tech as well.
- (December 10, 2003) The [Buzz-o-sonic] equipment is working fine. We are using it to measure for internal flaws in ceramic samples.

- (June 8, 2004) At the moment we are not considering to buy any apparatus to detect cracks, however we still expect that it will be necessary in the future. Unfortunately it is more or less impossible to say when. Buzz-o-sonic is still the only apparatus that have been shown to work on our material, so without doubt it will be one of the first things to look at.

- (April 29, 2004) Again I am impressed at the quality and depth of your report. Your results confirmed my suspicions but I didn't expect it to be so clear cut. My boss is intrigued by your results and the fact that the damping measurement can be done.
- (March 29, 2004) What a fantastic [Buzz-o-sonic testing] report! I am blown away by the level of detail you have included. I can't wait to show the boss.

- (December 9, 2003) I treat your measurement as a very accurate because I have checked the YM and SM measured by the Impulse Excitation Technique on the similar material (porous NiO/ZrO2) made at ORNL in Oak Ridge and their are very similar. The results presented by german scientist from FZJ in Julich are very close also to your measurements.

- (May 19, 2003) Dear Paul, ...Attached you will find an MS-Word with the draft of a manuscript in which we compare four different test techniques to determine the elastic properties of alumina, aluminum, steel and glass. We used four different techniques, namely, resonant ultrasound spectroscopy (RUS), impulse excitation (Buzz-o-sonic), 4-pt bending and nanoindentation. We used the demo version that you had given me in St. Louis a year ago (or two years ago?) and one copy that my post-doc had downloaded from your web-site. As you can see from the paper, the technique is very reproducible and has very high precision.
