A rather unusual review this:
Needing a connector for a welding gas bottle I researched the Internet and came up with this company who appeared to have the items I needed, so I placed the order on 23/06/26 and the items duly arrived. However they were not what I wanted and I realised that I had misinterpreted the sizing. Clearly my error.
An exchange of emails followed wherein I sent pictures of the gas-tap I needed the connectors for alongside a digital caliper to illustrate the exact dimensions required.
In the end it seemed that welding equipment components were not what this company was about and so I returned the items by Royal Mail on 13/07/26.
The value of the items being just £7.17 (plus VAT) I considered the cost of 'Signed For' not worth it and the postal charge for the return was just £1.55. (N.B. The cost of P&P charged when they sent the items to me was £4.99 (tracked) and the VAT was added on top of this so that the total bill was £14.59.)
Having received nothing from the company I emailed them, enclosing a photo' of the Certificate of Posting, but they insist that the items have not been received and that, "If and when returned we will happily refund." ("IF". Is there a suggestion there that I am lying about posting them back, despite the Certificate of Posting clearly showing that I had?)
To date no such refund has been received which leaves me out of pocket to a total of £16.14, (though I only required a refund for the items which would have amounted to about £8.65), and with the following unanswered questions:
If they haven't received the items then where are they?
Have Royal Mail 'lost' them?
What processes does the company have for receiving returned items?
Might they have been received but not recorded as such?
The sum of money I have lost is small in 2026 terms but all in all it's a bit of a bit of a 'dogs dinner' and an object lesson to me and to anybody else as a non-trade individual who looks to 'experts' for help and advice.
Perhaps I should have retained the items and found a use for them elsewhere? Hindsight!
In short if you are like me, avoid this company at all costs, especially if you are considering spending a substantial sum.
Customer satisfaction does not appear a high priority for them and their refusal to take a customer's word (and evidence) as truthful is disappointing to say the least.
Much better to stick with Ebay whereby the system properly supports the customer.
Did I obtain the required items in the end? Yes I did, from a very helpful specialist welding supplies company who understood immediately what I needed and the purchase was made where?
Ebay of course.
In conclusion perhaps the clue is in the name: I needed a gas connector and their title mentions only 'Fluid'?

Fantastic supplier, provide VAT receipts quickly, respond to any technical and commercial enquiries, great quality products and short lead times.

Horrific customer service, incredibly rude, typing with words in capitals as if they were shouting the email, no politeness or patience. DO NOT RECOMEND.

Don’t buy here. Customer service is terrible. The products you order are not what you receive. If you request a refund, you have to return the items yourself and pay for the shipping costs.

AVOID THESE PEOPLE
Total shambles , rude and lacking in customer service . I felt so angry and upset by there comments to me . Read through the reviews.
Awful !!!

Paul who spoke to me on the phone was very helpful with what was probably a small order to repair my classic car, most companies won't give you the time of day. The parts arrived in good time - great job, would recommend 👍

Very friendly team! Very supportive! They are very nice a helpful! Very professional! I didn't know exactly what i was i need but they were able to find out! I have been in 10-15 shops and nobody had the parts i was i need but they have got everything you can imagine! High five and thank you very much again! Well done!

I have a concours condition car and require new breather hose for the engine. The original hose is red cotton braided over rubber. I contacted AFS and they were so helpful in trying to locate some for me. Although none of their suppliers produce red cotton braided hose now, they even contacted certain people in germany trying to locate NOS for me. So, although not successful in locating the red hose I highly recommended Advanced Fluid Solutions for their helpful and friendly service. They did everything they could to help

Great quality products, very reasonable prices.
Would be nice to have a tracking number to follow shipping, and when I sent an inquiry by email I never got an answer.
Nevertheless, always been satisfied with the products and I will certainly order again!

Shocking customer service - their phone service is a nightmare! no one knows what they are on about
