Review on 💪 Efficient Oxidization Filaments Hand Pump with Versatile Options by Jacob Schmidt

Great concept. The bags, seals and pump are well made, but... some bags have small holes in them when packed at the factory. I liked the bags so much that I filled them with air, sealed them and dunked them under water to find holes. After the sacks had dried, a small amount of transparent packing tape was taped over the very small holes. Tape patch works fantastic! Why do I take all this trouble to mend the pockets? These bags and pumps really work! Dry filament prints very smooth with very small streaks and bumps. I was also wondering if I have a leak in my pocket in the future, I will know how to fix it. All bags are working great so far. You may be wondering why I should give this product 5 stars if it isn't perfect. Good question. The answer is that they have excellent customer service and a product that works, although it may need some tweaking.
