Update: my order was cancelled and the notice says a refund is in process. As far is it goes between us, the matter is settled.
A factual assessment based on user testimony is as follows. The facts show all of his UK customers get their purchases in a timely manner, but overseas USA customers are a different story. The one exception to UK fulfillment is the winner of the 2022 Halloween raffle (more on that to follow). Some get great communication and updates, some get radio silence. He seems reluctant to provide refunds to those that request them. This is not an opinion. These are facts based on information gathered first hand that anyone can read.
One USA customer has been denied a refund due to materials having been purchased for the order that was placed in 2022. However materials stated are raw materials only, not specialized pre fabricated parts from other vendors such as valves or metal fittings, but resin and fiberglass and a laser cut motherboard; such materials would have to be on hand in his shop already regardless of who purchased a specific item. A shop of this level could be expected to have several laser cut motherboards or spares on hand for incoming or current builds. If individual hobbyists hoard specialized hardware, a seller would do that even more so to have a supply on hand.
Now on raffles. 2022 Halloween raffle for the Phoebe Spengler Pack was not clear on whether it was a finished item or product to be built. He states “all prize draw posts, this is a one off and this is the actual pack someone’s going to win.” Hence referring to the pack pictured. The winner of the 2022 raffle was under the impression it was a ready built pack, however they are still waiting for their pack now in 2024 being told materials are hard to come by. The winner that purchased a raffle ticket has yet to receive the item won in the raffle. The Frozen Empire pack raffle is pictured as finished and it is stated the pack pictured is the one to be shipped to the winner. This remains to be seen. Furthermore, it seems questionable to use raffles as a way to generate shop revenue rather than sale of actual goods. Mostly all raffles in our fandom are for charity or are free entry, not ticket sales for personal gain.
Now for my opinion. His builds are obviously first class all the way, quality, accuracy, workmanship, everything - not only for pictures but all his client testimonials. Where he falls through is communication to clients. He is unwilling to admit any fault whatsoever and will place the blame on the customer for holding him to task - upon making public statements on my personal experience in this forum I was told that I was slinging sh*t and out to sink his business when I stated what has happened and how I feel about it. I - the customer that paid him - am the problem to his business. Rather than an apology, empathetic statement, or trying to reassure my doubts, I got snarky remarks and off handed quips as if I was beholden to him for his product. At this point regardless of refund I no longer wanted his product for the level of arrogance it represents to me, I could not have that product in my home.
Conclusion. If you are UK based you’ll likely get your order on time as promised and you’ll be happy. If you are based outside the UK proceed with caution.
How to improve based on user feedback:
Gain a little bit of humility and realize that his customers are the reason his shop exists, not the other way around. Address communication, perhaps take payments in installments as a build proceeds for larger items. BE TRANSPARENT with customers when there is a delay, inform them of a status change right away.
If you are in the USA and feel you have been the victim of foreign fraud you can file a report here:

With that, my dealings with Proton Props are finished.
Projects: 
granted Im not gonna call him a crook and I have been very relaxed about my whole experience and give him plenty of leeway with all the issues that have arisen. But you arent helping him or gonna sway anybody who is pissed the f*** off.
