Lost, not looking for an argument - thanks for the troll sledge! - just thought you could offer us all a little more than 'I feel they are'.
If this fridge slide was designed exactly like a regular fridge slide but cost twice as much, maybe it could be criticised as over-priced. If there were spliminty-teen other drop-down slides of similar quality but offered at a lesser price, maybe it could be criticised as over-priced.
But it's not. And there isn't. Even the most casual of glances shows it's got twice the 'bits' of a conventional one-plane fridge slide and there are significant user benefits compared to other slides. Of course its design makes life easier for short people... a related benefit is for those with families, it allows smaller (possibly shy) kids to get thier own drinks without asking Mum & Dad. Plus, in some vehicle fit-outs, it allows fridges to be poked into places where they may not otherwise be carried or easily accessed on a conventional one-plane slide due to vehicle tailgate clearance etc
Disregarding any 'bling' value
of the product I reckon many, if not most, experienced campers/travellers will recognise the plusses/benefits in the design, even if those benefits are of little or no use to them.
The product does have drawbacks that may or may not be an issue depending on vehicle fit-out and the customer's use situation: It is heavy (25+kg) and cannot be locked in the open position like many/most other one-plane slides (possible roll-back if the vehicle is parked on a slope). Some model fridges are a tight fit. Routing of the fridge power cord must be more carefully considered than a regular slide (loop it through the rear-most fridge handle). Like any fridge slide based on roller elements, there is the risk of dirt damage if used in an unsealed or poorly sealed vehicle. As the intention is for this product to be used in a wagon (with an assumption of reasonable dust sealing) this is not much of an issue. I am aware there were one or two quality issues on the earlier models that - to the best of my knowledge - have been corrected/refined by its manufacturer.
Expensive? Compared to other slides, yes. It is roughly double the price.
Value? That's up to the customer to decide, based on his/her usage and vehicle fitout situation, with the product features/advantages I hope I have adequately outlined above.
Over-priced? Compared to conventional fridge slides in the market, its extra features, usability - plus extra component and manufacturing costs (whether chingchang or Aussie) - I don't think this criticism can be objectively or fairly levelled at the drop-down slide.
Rambo, I'm sure you'll be happy with how it works and the manufacturer back-up etc
