We have worked with TKS on several projects and I have yet to find any major flaws. The only one I can think of is that they stay busy but that is normal for a good integrator. We have tasked TKS with project ranging from $10K to $1M and they provide the same customer care regardless of our investment. They WILL stand behind their work and provide customer support when needed. Again, they are a strong outfit which is why several of our Snap-on plants do business with them.
