Sorry you're feeling confused there Dad of Iad!
My comment wasn't to say that we never take into consideration what companies and PRs can tell us about their products. We work closely with them to ensure we understand product features, what a products claim to do etc, so our reviewers know exactly which claims to pay special attention to as they put the item to the test. This is especially crucial with safety products, where the right car and correct installation is vital. As we don't purchase items, the company must send the product to our tester. I was attempting to explain that it's not a case of us just sitting back, awaiting a PR to offer us an item to trial as and when they like - we work hard finding out what's being designed, chasing up items we know are in production and of interest to MFM users. I hound many, many people in the industry!
The rest of Britax's main car seat range I believe we have covered and this is a car seat that I hope to periodically return to and push for a review. However, I cannot force a company to provide an item for review, and given that this isn't such a core product in the range, but a specialised item that can only be fitted at 19 locations in the UK, I have to prioritise my reviewing efforts and ensure car seats UK-based parents are most likely to encounter are covered off first.
As Britax states on its website, "The MULTI-TECH 2 is a car seat developed for the Swedish market to comply with the local standard. BRITAX does provide this seat in other EU countries but this type of car seat requires skilled and trained installation. Please make sure you test and purchase this seat by only taking your car to a specialist retailer with trained staff to make sure the seat will be installed correctly."
I feel the answer to your ending question is mostly a matter of how you choose to interpret the phrase "offered up" - I chase items for review, and as manufacturers understand how valuable independent reviews are, they meet my request for a sample to trial. Some happily offer the car seat, others I must pester and pester. As I have been around a while, many companies know as soon as they have a new item, I'll want to test it, so they come to me immediately without pestering required! As for the rare one we can't get reviewed (as is the case here), if you count this as "MFM will only review seats offered up by the manufacturer", then the simple answer, which doesn't best reflect our process, can be taken to be yes.
