Hi David
Before I try to answer you I think we should be aware that it is your financial interest as to the future of the Airbeam.
-----------------------------------------------------------------------------------------------------------------------------------
You say I've been researching Airbeam for a good period of time to see all the negatives and positives regarding the product. Having read many reviews and seen the product in the flesh dozens of time i have formed my own opinion.
-----------------------------------------------------------------------------------------------------------------------------------------
However, you must not forget the thousands of customers who do not suffer any issues with their product and therefore do not write a review regarding that product. In fact, most people
-----------------------------------------------------------------------------------------------------------------------------------------
Until we know the percentage of returns and complaints and the number of units sold how can you say that.
I personally have read about more problems with the Airbeam than any other expensive tent,in the years I have been using the Internet.
I wont go on David it seams truth and mutual discussion upset too many people these days.
But answer me one question .Firms like Vango don't make miss prints about critical features that can fell a tent.in my opinion, the tubes and seams in the percentage of tents that became defective were not strong enough to withstand the force of 5 PSI. and the reduction psi to cover their quality will no doubt allow tents to get blown down.Once again this is ((my opinion)) as an engineer
Knowing that a tube must have enough pressure to withstand strong winds, because the tube is guyed solid and the tube is restrained like it is strong winds will squash the tube and allow it to fold if enough pressure is not in the tube to resist 3 psi is quite adequate to hold the tent up while it is guyed, this as I said in my previous post Kamplet state to increase pressure by 25% if strong winds are forecast With all 18 guys fitted on just the basic tent.
This Post is the reason fellow campers spend many hours to read about campers who have bought tents and had problems ,my guess is that only a small percentage of camper join and post on forums and if they have had problems we want to here.
It is well known that if you require a true review of any product the user is were to go to,and honest forums who do not take the retailers adverts like this forum are the place to find out.
My own website that is read by campers from across the globe is not used for this type of information.
David.
Products that are made in a QA regulated factory and are fully tested not 1 or 2 at the4 start of a project,But on a regular basis throughout manufacture will soon find any faults or weakness in a design and can correct it. The campers in the UK should not be Final inspection for manufactures products.
As I have stated all along the Idea is fine the maths add up the QA let it down . Because it is inflatable their are far more items in the build that can become defective.
Once again I wish Vango good luck and hope they achieve a successful tent for my fellow UK campers and their families.
OK I believe the saying is "Im out of her" I have no more to add

and as David and I said we will just have to wait to see what 2012 brings to the AIRBEAM.

Rex

PS ) water ingress at the seams where the tubes have been overfilled.
2) exploding beams again down to overfilling the beam.
Were is the proof that the camper over inflated the tubes is it not possible that the camper acted within the spec and the tents that leaked and exploded were not as strong as the others ??? bad QA.
