I highly recommend it. I just finished the aforementioned Yuxin Blue, and it's fantastic. I'll admit I was skeptical about your enthusiasm for Gaussboys magnets, after all a magnet is a magnet, right? But comparing the Gaussboys magnets to ebay magnets is night and day difference.

Yeah it's just finding the time and patience for the 4x4!
Yeah, I really like Gaussboys. Great quality magnets and the seller is really supportive of what we cubers are doing with magnets! Like everyone else, early on, I bought magnets off of eBay. It didn't take long to find out that the consistency and quality of those cheapo magnets was not very high. Consistency of strength and quality if plating is very important!
Now... time to make Prototype #10 GTS2 M! Just got my N35 5x1s from magnets365. Those silly clowns literally mixed the 5x1s in with the 4x2s. Ugh! Thank goodness I didn't order a variety of strengths!
Their quality isn't particularly great, but their N35 4x2s work well in the Valk and Air. I'm curious to try the N35 5x1s. I'm thinking the end result is going to feel like my Cubicle Labs regular GTS2 M.

I was actually pretty surprised how quick it was. Roughly 2 hours start to finish, and I'm no speed demon. I've now magnetized a Big Sail, Yulong, Aoshi, Weichuang, and Blue. The 3x3s were obviously easiest, and the 6x6 was hardest, but I'd say of the 4x4 and 5x5 the 4x4 was actually easier because of bigger pieces. It's really pretty comparable to 2 3x3s.

It's the putting it back together that I'm worried about!!!
EDIT: Actually part of the order had fallen out of the bubble wrap and I just found the missing magnets on the kitchen floor!!! (Well, heck! Magnets365 let me down. I had ordered 300 N35 4x2s, they sent 250. Ordered 300 N35 5x1s, they sent 196!)

It's significantly easier to assemble a magnetic big cube than a non-magnetic one.
That was another thing I was happy with about gaussboys: I ordered 48 and 144, got 54 and 150.

I ordered 500 4mm x 3mm N35 magnets from an eBay seller that I had used before but I received 3mm x 5mm which are useless. They were good and said they'd send the correct ones when I got in touch but they never arrived.

Dang, that's terrible. Maybe one good thing about eBay purchases is that you can leave feedback on the seller.

They've been ok before. Unfortunately as I was waiting for the new lot I missed the 30 day guaranteed ebay refund. I'm giving them one more chance before I get the money back through PayPal.
The ones they sent me are worth twice as much as the ones I need. I have 6 cubes waiting for their magnets.

Silly me. I just found the missing portion of my order under my kitchen table! Apparently a rather long stick of magnets slipped out of the bubble wrap and hit the floor.

Hey guys, I'm new to this forum, and I just wanted to ask some questions about a magnetic 4x4. Specifically, I want some advice on which magnets to put in a yuxin blue. I'm mostly new to making magnetic cubes, so I would appreciate any advice. I guess I still don't know what I prefer in a magnetic cube. For example, I know a yuexiao with 4x2 n48 magnets is a little too strong for me, but a chuwen 2x2 with 4x1 n48 magnets is just about right.

For my Blue I went with N38 3x2mm in the edges, and N35 4x2mm in the corners. It feels light, lighter than the QiYi WuQue with the same config, but the magnets still work well ... for me anyway

I used 4x2 n38 for the outer layer, and 4x1.5 n38 on the inner layer. It's a fairly strong magnetic feel, and using n35 wouldn't hurt anything, but I'm very happy with it.

Where can I find the 3x2 mm n38 magnets? Also, would it be possible to use a lower grade 5x1 magnet in the 4x4 instead of the usual 4x2 or 3x2 magnets?For my Blue I went with N38 3x2mm in the edges, and N35 4x2mm in the corners. It feels light, lighter than the QiYi WuQue with the same config, but the magnets still work well ... for me anyway

Along the inner slice of the yuxin 4mm is tight. Elsewhere you might be able to get away with it.

If you're in the USA, DMCubing has recommended Gaussboys. I sourced the 3x2's locally, thankfully. Everything else I've looked abroad for.

I think I'm finally done with eBay magnets. I just received an order where 10 magnets are each tightly wrapped and taped in bubble wrap. I have 20 of those to open now.

After measuring my Blue, I can see what you mean. The inner part, magnetized like a 2x2, will only work with 4mm magnets and smaller. However, I measured the outer layers with some 6mm magnets I had lying around, and I saw that you might be able to use 6mm and below, but it's really tight, and I can't guarantee the end result will be aligned properly. So, I'll probably try the outside with N48 5x1 mm and the inside with N38 4x1.5. How does that sound to you?
Also, I don't have any calipers handy, so could anyone here do me a favor and measure the gauge of the yuxin blue plastic (edge and corner)?

I think that should be ok. My only concern is that your outer layer magnets are quite weak relative to the inner layer ones. According to the calculator on the KJ magnetics site the 4x1.5 should generate roughly 0.14 lbs of pull force per edge (0.56 lbs per slice turn). I like that on mine, but I think it is on the high side of what is optimal. Mine is set up with the 4x2 n38s, which according to that calculator would be 0.1 lbs per edge, or 0.40 lbs per outer layer turn. It is clearly lighter on the outer layer turns, but I think it's a good balance. Your 5x1 n48s for the outer layer would have a pull force of 0.07 lbs per corner, or 0.28 lbs per outer layer turn. I suspect that is too much of a discrepancy from the 0.56 lbs on the inner layer.
Also, I'm afraid I don't have any calipers handy, so my numbers are based on the estimation of 2mm of plastic between magnets. That's pretty close, but it might be just high.
