Bubble 75 Mechanical Keyboard - Premium

Was looking to replace my GMMK Pro and Bubble75 seems to be the perfect replacement! This keyboard has no visible screws on the outside which is super clean. The side profile looks great. I went with the blue color and it'd say it looks better in person than on renders, it's definitely on the bluer side than grey.
Assembly isn't too hard, the keyboard comes with a LOT of foam, so lining them up was a bit of a hassle.
The initial complaints of a very short daughter board ribbon cable was addressed, Bubble Studio included a longer ribbon cable and the install was much easier.
Overall very satisfied!

Really happy with my purchase – unboxing was a neat experience and everything is better quality than expected. The bubble theme throughout the board is also appreciated. Decided to purchase FR4 plate as an extra.

Once again, glad I decided on this board!

I have tinkered a fair bit with this board. People are very excited to find a Jelly alternative that is easier to get a hold of, but that isn't the only sound profile this board is capable of achieving. Without case foam and PE Foam, this board has a super nice clacky sound. It doesn't NEED the case foam to sound great! I urge anyone getting it to atleast try with & without the case foam, and also give it a try without the PE or EVA foam. I'm not saying that you'll prefer them over the PE sound, but there definitely is more to this board than people think.

Overall, comparing to the GMMK Pro, I found that this board ticked all the boxes I needed ticket for an upgrade.

The Bubble 75 custom mechanical keyboard is one of my favorite custom boards. The typing sound and experience can be tweaked by playing around with the case foam, stand-offs, plate material, and plate foam combinations. I built mine with PC plate, 1 case foam, some of the stand-offs, plate foam, eva pcb foam, tape mod, GMK stabs, and holy panda switches to create a more firm typing build. The turquois blue case color wasn't as turquois as I'd originally thought, but it worked out well as you can see in the picture below. The bubble 75 is a solid value for the money with good build quality and customizability. I also bought a brass plate so the next time I open this up, I'll switch it up for a very different typing experience.

The only odd thing is that the daughter board and ribbon cables cannot be purchased separately so even if you buy an extra PCB, you will still be missing the extra db and longer ribbon cables for the rainy day. Not a show stopper by any means, but I thought it was an odd decision made by Velocifire. I'm hoping they'll make it available for purchase in the future.

This was the first keyboard group buy I went in on and it definitely didn't disappoint. I loved the sound of the Jelly Epoch, but couldn't get my hands on one. The board sounds great both with and without the use of the PE or EVA foam. The anodization on my board is very even and top notch. I built mine out with the EVA foam, long pole switches, and GMK Hammerhead and I absolutely love the sound profile of it. Very nice and bouncy typing feel.

The only reason I can't give it five stars is that god. Damn. Ribbon. Cable. I've never felt so frustrated trying to put a board together. Not a very friendly or overly fun building experience (I want so badly to try out other plate options and foam configurations but... the idea of dealing with that cable again...)

The standout feature of the Bubble is definitely its sound and typing feel. It has a lively signature if you opt off of the case foam (But leave something to prevent shorting the PCB; tape mod maybe). I have mine mounted with mint chocolate chip switches, and it sounds and feels good to me. The looks are obviously subjective, I think it's quite an unoffensive design. My only gripe is I do think that the front height is a tad too high by 1-1.5mm. And I do wish the USBC port was centered to the case.

Couldn't get your hand on a jelly epoch? Bubble 75 is 95% the same thing, that sound signature with the Pe foam and forgiving flex is truly addicting. As a daily driver, I can't enough of it with long pole stem linears. Every key I tap is full of pop!
