Hear me out all the way to the end, please.
No, not the same. Different industry, different treatment of parts, different costs, different expectations of equipment, etc etc. You also don't place a PC in the sun and rain to test and use it.
Also, PCs have a different benchmark not affected by location. It will always be X speed, as advertised, unless it's malfuncitoning. If it is, no one would argue that a replacement or refund would be in order.
Cellular system speeds depend on cell towers, plans, location specifics, etc. All controlled by cellular providers and their contractors. Many variables not under the control of the equipment itself. Someone would want to return it if the system doesn't get a subjective, to them, speed metric that is of zero fault of the parts manufacturers or the store assembly team for the custom built system; but it is still expected to be returnable. This is not the same as a PC system, their capabilities are not affected by outside forces and variables, especially not effected by the customers location.
On another note: If you purchased all of the parts separately and assembled it yourself, drilling and all, you wouldn't expect to return it, but if the haven builds it you should be able to? How is this different?
If you could put all the parts back to their original state basically untouched, just like you would with a home PC build, then that would be a different story I'd think. "None the wiser"
Look, I'm not arguing that it's not a lot of money and investment. I am saying you're not out all of the money, you can sell it, that store doesn't take back used items, especially custom ones. It's in their terms on the site. At least at this point.
I would bet any store that sells similar items would not. Try sending just an outdoor enclosure, with holes drilled in it, back for a full refund to any business that sells that sort of thing. I don't think it'll get approved.
I think you are saying you can't resell it for anything near what you would potentially pay, but that the store should absorb that and somehow be able, or want, to resell a now used product at a loss. Not because the product is a bad product or malfunctioning, which The Wireless Haven would 100% back with a fix or replacement, but because your location may not provide the speeds you wish to gain from it.
From my own personal view, it is a very difficult decision to not take all returns back from all customers. As this conversation shows, the amount spent on such items makes it a very emotional reaction when someone hears they may not get their money back in full from the store. BUT it always proves out that the reason people want to make these kinds of returns is for problems that are
100% out of the control of the store, and of the manufacturer of the items in question. Yet, it is still expected to be the store that takes the loss. Again, this is a different conversation than one on support for a malfunctioning product, or damaged item upon receipt. That is 100% always going to be allowed and accepted for replacements and full personal support for every customer. But it's being put in the same barrel, so to speak.
As an aside, I can personally say that everything will be done to ensure that these antenna builds are not being built better by anyone else anywhere. Period. They are also not supported after sale better by anyone else, anywhere. Period.
And if you want me to seal the deal, email the store with my name in the content and ask about a little upgrade to the system in question and I might be able to get you a little boost in product. Keep you on the cutting edge.
