No problems with Vitality 4 Life. Good communication and quick delivery. The BioChef blender itself is a mixed review. Cons: - does not live up to claims for vacuum blending if instructions followed. Separation of ingredients is as fast as non-vacuum blenders. - very noisy, 6dB up on 2 other blenders I tested against. - cannot be disassembled for cleaning do dependent on blending detergent and water mix no way to physically clean blades. - pulse cleaning blows the lid off whichbis very messy Pros: - if blending program is run twice, fully blended results and no separation at all afterwards - quick run of vacuum function before pulse cleaning, keeps the lid on tight so messy cleaning can be avoided
