Post Subject: What about models PP1050, PP3000? · Late-2010 stock units treated as well?Posted by spytsi on: 6/20/2011

Hi Romy and all forum members,

I've been following this entire thread for a couple of weeks now, since I came to know about PurePower products. Needless to say this was a source of valuable information regarding bad off-the-wall electricity and this company's approach to dealing with it.

Everybody here remembers that Romy's initial acquaintance with PP products was through model 1050; at some later point he upgraded to model 2000. Since then quite a few user opinions appeared on this thread to discuss how did the PP1050 develop over the years. Where there any PP1050 users to also experience buzzing or humming of any kind? Did the —seemingly problematic— revision/upgrade for PP2000 during late 2010 also affect the sonic behavior of revised/upgraded PP1050 units in a similar manner? Were there any PP1050 users that at some point experienced similar sound from their newly purchased units, performing significantly better when running on battery than on AC regeneration mode? Any feedback on model PP3000, introduced during late 2010? It would be interesting to know, especially from thread readers that might have not yet posted their experience with PP1050 or PP3000.

On a side note: what does the labeling of PP models (following their 4-digit number code) stand for? Maybe "i" for international (120V), "hv" for high voltage (230V)?

Romy, since you are the person who discussed extensively with the manufacturers the imperative need to deal with the problems encountered on their revised PP2000 units (Nov-Dec 2010), did they recognize the need to apply this (hardware?) treatment for this bug on their entire product line (1050, 3000, both i & hv), or just on the 2000i/hv devices? Apart from implementing this treatment on their product line prospectively, did they also happen to do so retrospectively = did they fix all already stocked late-2010 PP units before being sold to customers?

Regards,

ST
