Pop'n Music Sanwa Button, switch and spring set (OBSA-100UMQ)

The #1 source for these specialty buttons, packed perfectly and once they were in stock shipped and arrived quickly and without issue. Will keep an eye out on new stock for the future :)

We had a setback in the export (to Spain) but i was informed about the process at all times. The item has arrived and everything is perfect. I will buy here again.

For anyone curious about Sanwa buttons and Blue Spring Express, I bought the button set linked here. The package showed up today and I just finished installing everything. Without a doubt, this is my favorite purchase of the year.

All of the items were brand new, had plenty of protective packaging, and Nitram provided amazing support. I am a newbie when it comes to arcade maintenance operations. A few random events stumped me, such as stuck buttons and high pitched resonation. Nitram was there each step of the way and pulled me out of every hole that I fell into.

If you are considering an upgrade, hopefully my recommendation is enough to push your decision forward.

Thanks again, @Nitram. You rock!

Reasonable shipping time and excellent communication, and it's great knowing that the set comes with everything you need.I used these on my DJ Dao controller and had no issues other than some slight nudging when inserting the LED bulbs. Overall, I'm really happy with the quality! These buttons really do elevate play to feel closer to an arcade experience and get rid of the higher frequency resonant sounds that I had when playing with the stock buttons. Highly recommended for those who want a premium experience at home!

As a long time Pop'n Music player, I've been debating on getting sanwas after playing with samducks for 2 years. Aside from the price, the one thing stopping me from upgrading sooner was the hassle of going through a proxy service to order a set of sanwas. The moment I discovered bluespringexpress I knew it was the perfect opportunity to get my hands on these buttons! The ordering process is MUCH easier and hassle free! The owner of the website was very helpful and kept me updated with my order, as well as tips and advice on maintaining the buttons!
Now for the buttons themselves, they arrived with safe packaging and labeled straight from the factory. Because these buttons are brand new, you may experience some "sticking" for a while. Personally I haven't had any issues, even with me installing the 100g springs. These buttons feel very crisp and fantastic to play on, clearing 37-40 level songs has been a breeze! (My current skill level.) I've been told they'll feel even better after a month or so of play to break them in!
Side note for those with DJ Dao's controller, these do fit but they take some force and positioning to get them in right.
Overall I've had an amazing experience and definitely recommend upgrading and avoiding proxy sites, just get them from here!
