shark shk1500m, is this alarm junk?

No we still have a few genuine Cliffords, they sell 2 Cat 1 models,the Concept 650 Mkll and the Avant Guard 5.5X. These are G5 with the later (Trilogix?) remotes. They still use Wizard software. The UK Viper Cat 1 equivalents, 460VX 480VX 2 way using Bitwriter software are MUCH slower on remote response, either trunk release (2+ secs hold against instant for the Clifford product) or disarming the unit once triggered. Lots of problems with the 2 way LCD remotes on the 480. (Quel surprise!) Failure rates even with the current product and remember 2 immobiliser circuits, about 0.001 failure rate on the CPU, about 5% on the battery back-up siren. The failure rates quoted by Segal on Zenesis product are completely unacceptable Lastly and maybe I'm being paranoid damning without knowing, but I have tried (once) clones of this product. It was so awful that even the customer wanted it binned and replaced with DEI product.

FWIW: Thanks to Sharky for asking - I have loved the responses - in particular ChrisL's itemisation and comments, but also ALL the rest (even you Howie). (That's jest - Howie knows my respect.) And whilst FleaBay need not be bad (some things are quite the opposite - better quality at lower prices), the problem is as usual knowing the product, and seller. But to get this sort or REAL feedback, knowledge & experience (whether right, wrong, unique, subjective etc) is INVALUABLE. (Hey - someone should put this info on the internet! LOL-again.) Thanks to ALL!! FWIW#2: (For What's It's Worth... aka 4WiW etc) I hate spending, but I buy quality. Where quality is required, I may spend three times as much, or more. (IE - for smaller or critical items. For expensive items it's often risk the cheaper - especially if the replacement is/are already paid for by the savings.) In this case, a crap alarm is no alarm. A crap alarm can even damage a vehicle (ie, ever vandalised an annoyance?) But in this case, to save a "mere" $100 or thereabouts (even to protect my $1,000 45 year old ute) is negligible. If in doubt, I'd pay double. Then considerations like lost remotes etc... That alone almost settles it. (And too oil-pressure switching etc if that can be determined - but usually it can't.)
