We looked at several companies (including Rees) for our RFP. We chose Veriteq based on ease of use, flexibility, ability to install ourselves & cost. The company's data loggers are on the space station, batteries last 10+ years, the company itself is very customer service oriented (so are the others). We are a multi-site system, have the software in one location and data loggers (so far) in 4 others. The ability to self manage the system was important to us as we tend to move things around. Having a vendor come in is pricey. The software is incredibly easy to use.
