The problem with bloggers in a reviewing sense is they have their own bias and I think people see that
I suppose the other argument against is the risk of sending something to a completely independent reviewer is receiving a bad review or even slightly negative/ average comment so why take that risk when the norm works ok(ish)
There are brands on this forum who have done what you suggest with "influencers" and I think that was received very well, though it is hard to expand to the wider range of potential customers. The reason I say that is that if we are really honest kit doesn't really vary that much compared to other industries and it is a saturated market of everyone doing things pretty much the same and the average cricket consumer isn't really missing much by buying whatever looks nice, nor does the average buyer think about buying a bat or kit more than walking in to their local sports shop and going for whatever they like the look of.
I like @sarg 's video reviews for honest thoughts and subtle differences between a wide range of bats though that is a bit too geeky CBF for most
I agree, Sarg's content is good and that's probably the best out there at the moment.
I did enjoy the Cricket Insight content when that was going strong and there was a gear test then, which at that point I was involved with Vantage and the lithium bat won an award for the best performer on the day. Whilst I completely get that it's a saturated market and the majority of products are fairly similar, this will make brands put more effort in when designing kit etc. Not only that, there is much more to judge a product on than the product itself - customer service, ease of purchasing, information with the product, packaging and so on.
Regarding bloggers/influencers benefiting from something like this - there is much more than just receiving free kit to review, such as being paid every time someone clicks on a referral link, influencing a customer to purchase, having paid for advertising banners on their website etc. Whilst this is stepping in to the same territory of the magazines, there will be a fine-line of when it (hopefully) goes from being a hobby, to a full-time and profitable job. So different to the magazines that seem to have to please everyone - the blog(s) should have their own voice and their own personality and as they are a real person/voice - they will have their own opinions on what they do and do not like, otherwise they will be the same as the magazines and therefore become pointless/irrelivent.
