Just want ed to fetch this up again as will be getting an ets system, ready for use this year, in a round about sort of way have been given permission by club sec to use 1 ( even though he hates them ) :-) now maybe best ets is not the right word, would just like to know pros and cons of any of the systems, good or bad, dont want any negatives of why ets should not be used. Unikon? why does it need all these updates etc? and do any of the systems come with sms service as standard? and how effective are they used on a car battery? as have no electrics at my lofts. thanks for any help.
