Ok ive been wanting to ask, i use the ramps1.4 with mega 2560 as normal for repraps. Mine works fine. I got mine from a cheap ebay china source and got bith boards for 13$ total. Why are the (?same) boards sold locally like makergeeks web site for 115$! It seems outragous that is the same. Ive even seen diy builds with posts to the expensive ramps and arduino boards. As long as this is working im definatly buying the cheap versions as the electronics are what vamps the build price.
I’ve bought arduino boards from china that worked fine, and others that refused to work at all. It’s like any other purchase: you can go cheap and hope that it works, and sometimes succeed, or you can go expensive with the expectation that it’ll be a high quality product.
The differnce is between a safe printer and a burnt down house. The cheap ones work mostly but sometimes the mosfets on them malfunction and in worst case cause a fire.
As John says, most Chinese components are hit and miss. When it’s things like bearings or hardened rods you can order extra and just use the ones that are in spec and you’ve still come out ahead. But when it comes to things like electronics, you may do some real damage with the bad ones.
It’s likely that most, if not all, components on the Chinese board are knockoffs. It’s also likely that a few of the components are also under-specced compared to the original design as a cost saving measure.
Whether or not that causes a problem will vary, but FTDI is known for bricking devices that use counterfeit chips through driver updates. And cutting corners on power systems components (which are usually the most expensive) can result in a printer that can’t push as much power as you thought it could, or which suffers early component failure where the more expensive board wouldn’t.
There’s also the aspect of the expensive boards usually (but not always) supporting the people who designed them and who contribute to the 3D printing community, while the cheaper clone boards don’t. The US sourced boards also generally have some degree of support available, while the Chinese clones are sold as-is with no warranty or support.
So basically… you may be just fine, and you may have shaved ~$100 off your build cost, or you may experience one or more problems because of the cloned electronics. It’s all about the degree of risk you’re willing to accept.
Another thing about cloned boards, especially ones expected to handle a lot of power, is you can never be sure that the board itself is up to the task. Copper is expensive, so it’s a tempting area to cut back on, but thinner copper layers on boards makes for lower safe power carrying capacity.
The Chinese board, on visual inspection, may look identical to the US version in terms of trace layout and trace width. But without very close inspection it’s very hard to tell how thick the copper cladding on the board is.
The ones Makergeeks offers does look like a really marked-up Chinese RAMPS kit, it’s not as if it were a Ultimachine version. It might include a genuine MEGA controller, but it’s hard to tell with their wording.
Anyone willing to spend that amount of money for a controller really should consider a RAMBo anyway, it’s the RAMPS designer’s replacement for RAMPS. Or a smoothieboard.
As far as looks (and it may be like @Jeff_DeMaagd stated) my makergeek model ramps amd the cloned chinese version are identical i cant find any dissimilarity in them. And if they are 2 in the same i lose some confidence in makergeek as they advertise strickly their genuine products 
. Where can i garontee a non-knockoff ramps and arduino deal because i want to order another set for my next project and makerG was my source.
I should note that I own an Ultimachine RAMPS board (they made the original design) and it doesn’t look like that. The board and part colors are different and even the connector textures look different.
I actually got a bum/broken chinese board the very first time i ordered and they sent a replacement but it was shipping damage which i think ebay required them to replace it
At mrrf I realised one of the clone arduino due I brought for use with ramps-fd handles aref wrong (I could only read 0 or 4095, nothing in between). Lost several hours, so consider what your time is worth.
