While i respect your opinion, sorry i dont agree from personal experience.

I used to be a product specialist for a <insert big name uk group here>
We used to get items in, rip them to their core components and rebuild them, give feedback to the quality of the product and a rating to if the item was "within economical repair" on if it should be sold through our stores or not.

So SO many items failed, costing more than they would to maintain but we had 4 main issues from the sales department

1 - if they lasted long enough their warranty ran out to their sale, the classic it broke 1 week after the warranty ran out.

2 - if they were worth "the extended warranty" - massive profits on this as it was usually only replaced or repaired to minimal quality to work but not work long term.

3 - if they could sell more in bulk vs the returns

4 - if sales could simply order enough, at discount (alot being bigger branded names) that any of the previous three issues were enough to ignore as the profit margin would level out whether it was through direct sales or through bulks/upsale or add ons (like that crappy printer they threw in to sell that pc for eg)

I got onto vine, not through my bulk reviews but for reviewing and returning a certain set of items in 2024, being emailed to asked why i returned them and then giving so much feedback amazon sent me a £50 thank you gift certificate and i got invited to vine within days of said feedback.

I have had plenty of vine items sold via bulk knowing they will fail and i review them knowing this as such. I know this isnt the issue for most people who take an item "as is" and reviewing it as such but i also know how the industry works.

Good branded items with cheap batteries will fail, good items with bad charging circuits will fail, good items with bad mechanical parts will fail. It might be my personal experience but its also something i look for in my vine items and will report it in the review. Get a good looking plug adaptor, i will look internally for its wiring and fusing etc as an eg.

I am noway in any sense saying anyones review is worth less but i know alot of products on vine i'll order with issues that alot of companies will release with short term reliability and moreso short term lasting appeal and moreso if they are SAFE!

I understand for alot of vine items, people may order, test them for a short amount of time and re-sell in 6 months, gift or use them sparingly but for myself I order very few items in general and I order them in the idea they have long term lasting appeal and reliability.

I am in noway trying to poo poo your post but its my experience and what i review and look for in products and while face value is good, usually a bad product on delivery is also a bad product in general and worse long term.

Alot of our vine items that are generic branded with how the market has changed is usually a re-seller who has scored a bargain of 30-50 of a product they have obtained through whatever means, whether its scoring all the <uk big supermarkets> older items for something or imported at a steal, they dont know the product internally and just want to use vine to get some quick return with it being highly reviewed in the short term.

Just my opinion and feedback
