Thank you for creating the HV250 25Kv power supply! I bought the kit many years ago and have had just the best time with it, from making electrets, Bifeld-Brown experiments, ion blowers, charge experiments, electrostatic ant removal etc.




Considering the small size of my order I am very grateful that you guys still go to the trouble to take care of my custom like you do so I am most grateful as I do not believe I could get these items easily elsewhere – excellent care and service.




We've had some better than expected results for the biology experiments we were doing using the jet as is with the PVM400-220.




So fast it took 1 day from my order next day delivery awesome
 will be making more orders to come

Thanks again for all your help, your company has always been stellar to deal with. It's refreshing.




OK thanks!  I am very happy with the personal responses and could not ask for more!




It is really nice to know that there is someone who answers questions this fast in your company for future reference!





I must begin by telling you how awesome your website and the products you offer are. I can't find this stuff anywhere else. THANKS!





Thanks for posting the instructions and other information about your products. Your website is wonderfully informative in ways and to an extent that almost no other retailer is.

I first learned of you in the back of Popular Science magazine in 1985 as my interest was anything to do with high voltage and Tesla. Coming home from school to find a catalog from you and Lindsay publications was like Christmas to me. Keep up the good work!

Robert M.




I have built a magnetic cannon based on your design and it is awesome!!!!!





you guys are freaking awesome. Was in over my head trying this. I'm use to snapping modules together and stuff. Thanks a bunch!





Thank you for the part and response. The kit project was an interesting test and enjoyable. And it worked when done.

Monte D.





I recently ordered a stun gun kit from you...great website and products and hope to do a lot more buisness with your company. Many thanks

Benny D.





I recently purchased a PVM12 and have been very impressed, great little unit!






Hi. Just wanted to say thanks. I purchased the high output Ozone Generator kit a few months back. Finally had time to assemble it and tune it up. Works great. A very awesome project.


If I had the money, I would buy everything you have! Love the site.

I wanted you and your colleagues to know that the BTC30 arrived safe and

sound at my lab, and it already has been of great use in our work.

Back-story: It provides the 'trigger' to initiate arcing between test

articles which are charged using a much-lower-voltage capacitor bank, only

22KV or so.


Your folks packed it superbly, and it was properly tuned for good

performance "right out of the box." Just thought you would want to know

how well your BTC30 is performing in this unusual service. Put me down

for a testimonial!

I'd like to thank you for your great company, Information Unlimited.


It is a pleasure to do business with a company like yours.You stand behind your products, and are concerned about customer satisfaction.

Plz do me a favor, and DO NOT let the government push you guys around and take away your right to present science fair-quality informations that makes my creativity flourish!

W. S.





Thank you for your mail sir.

Unfortunatelly is very hard to find in my country all I need to make this device. Was just curiosity. Such a device is a nice piece in a fizic laboratory school but what can I say....is hard to build such a device here. Anyway your site is one of the most interesting on the net,congratulations

M. Fatu





Demo went great. If you have any sample lesson plans or demonstration ideas I would love to do another demonstration for the class.


Merry Christmas

Thanks! The first time I paid there was an error message that led me to believe payment had not occurred so I tried again using a different account (It had been a while and sometimes security codes change, etc…). Given the low cost I was not going to worry about it but I sure appreciate the customer service!


Warm regards,






Thanks so much for the refund, I know $4 isn't that much but it's the attention to detail. Keep on rockin' bro!








Thank you very much. I have manged to download the plans.

I made a mistake as I thought the plan for use on the Motor Car was different, hence the double payment.


I appreciate you honesty & integrity to refund me the second purchase.


Its been a pleasure to deal with you.


All my best,

Henry T.





Thanks for the refund... I've made a larger order and look forward

to doing business with you in the future.


Sincerely, Bruce P.





You guys are awesome. Thanks for the great customer service! I'll continue to support your business!

I have the BTC30 Tesla Coil--it's awesome and the reason I'm looking for info about bigger ones--and I'd like to build a Tesla receiving transformer to work with it.

Thanks, I got them. I downloaded your free PDF Catalog and I have to say you have some pretty cool stuff in there. You will probably be getting plenty of future orders from me. Thanks again.






Thanks for this message; it's nice to hear a personal touch from a company! I'll be buying more :D






Its a pleasure of being your customer -

In conjunction with a forum for posting project logs,

tidbits of advice and perhaps various tournaments,

I would be tempted to return and participate in

board discussions...







PS: thanks for the help on our singing tesla coil. It works really well. We got 120” arcs with half power.






Thank you very much for resolving this dispute. I am very pleased with

your customer service and will likely purchase other plans from you in

the future. I have already recommended your site to another person.


Thanks -Adam

Top service, thanks very much.






Thanks so much. You have gone above and beyond for someone who was ready to blame you for my mistake.

I must say I was really happy to find your site and all that you offer. To find out that you are a really good guy is frosting on the cake. You have a new loyal customer [who has yet to really buy anything].

Sincerely, John

John B.





Thanks very much for the quick action! It's this kind of service that me more likely to buy again!

Thanks for the follow-up. I will be ordering other plans as well. It is also reassuring that someone is aware of the activity between the customers and the company. Especially if the downloads failed and the plans are sent via email.


Thanks again!

Thank you very much for your feedback and for promptly following up on my purchases.


At first I was concerned that it might be difficult to get a quick response when I sent an

online email to get support, but now I deeply impressed.


Thanks to your help, I was able to automatically receive an email an email with a download

I was able to successfully download these plans as well, and soon after I made the purchase.
