Praise for Beige Bag Software and B2 Spice

"In spite of the little bugs your product is by far the best value in spice that I know of. I am only an infrequent user of spice but plan to use your tool more often in the future. I have used orcad and I found your tool to be more user friendly and well thought out. I have nothing but praise for your software and your software support. Your support group is always there and always helpful.

Thanks for a great product."

===============================

"I teach a course on electronic instrumentation for biological systems at the Senior level here in the Biological and Agricultural Engineering Department at the University of Arkansas. There are usually on the order of 20 students in the class, although it seems to be growing, and I had 25 students last Spring. Occasionally, I get a couple of grad students from Electrical Engineering, primarily because of the applied nature of the course.

We cover a fairly wide range of topics from a review of basic electronics to applications of embedded controllers and data acquisition systems. I don't require the students to buy B2 Spice, but I encourage them to do so, and many of the assignments require access to the program. I encourage the students to buy the student version, and I try to make sure that we have 10 licensed copies in our computer lab. They are able to use the program quickly, and use it extensively.
I have found the program to be very helpful in demonstrating and/or designing both analog and digital circuitry."

"I have used almost every Spice program in existence over the past 20 years, and I consider yours to be the most intuitive, powerful, and price-competitive on the market today."
