stomp –
Print quality is amazing. Customer service was even better when I didn’t know how the hell to install the trip. Incredibly happy with my purchase.
Elliott Balancad –
Would this work with MAC5K??
DEEPLINETACTICAL –
Firstly, Im DEEPLINETACTICAL on youtube and I do reviews of all things 3D printing 2A. I bought from ursa secretly to give an honest review on my channel. I have been nothing but impressed with this company thus far. I bought an SP5 leber V2, and it was doing numbers on my socials. After about 600 rounds of 9, my lower did crack. Contacted URSA and they had a replacement sent out overnight. Amazing customer support, and amazing quality. TU BABY
