I absolutely love the ULTIM8 JIG DELUXE KIT for my EufyMake E1! The silicone mats and fixtures make aligning objects on the print bed so much faster and more repeatable, and the spring clips keep everything locked in place while printing. Best of all, UV overspray peels right off the mats instead of ruining them, so I'm not constantly replacing bed mats anymore. Setup was straightforward and it has completely leveled up my print workflow. Five stars, highly recommend!
