Reviews Summary
Customers say these pump parts fit well with their devices and provide good suction. Many reviews mention the need to order two sets since each package contains only one valve and insert. While some appreciate having reliable replacement parts, others express concern about the pricing structure. Common feedback includes quick wear and tear of the silicone components. Frequent comments address the fast shipping and easy cleaning process. Some users note confusion about package contents, expecting a complete set for both sides. The brush accessory gets praise for reaching tight spots during cleaning. While most find these parts compatible with their pumps, a few report fit issues or receiving incorrect items. Several mention keeping spare sets on hand for backup. The silicone material feels soft and comfortable according to users, though some note it may become less effective over time. Delivery speed and packaging quality receive positive mentions.
