In life one must be cautious to receive promises made. This has never been more true than when purchasing renovated or used gear over the Internet, even when backed by Amazon's assurances. Therefore, I'm pleased to say that I have been completely satisfied with Aventis System's reworked Dell system recently bought. Setup, startup and updating of the computer was a snap, and it has performed better than expected. I was a bit concerned when unwrapping because Aventis apparently believes in minimalist packaging, but aside from some mild wear and tear, everything worked out of the box. I would, and probably will buy from Aventis again. One immaterial curiosity: Aventis calls this a 2018 model, but bits and pieces of the machine think 2015 is more realistic.
