I am extremely disappointed in my experience. Shipping took forever and it never arrived because Eufy uses the last mile carrier option to save money on their end when their products are already not necessarily cheap. Last mile means they save money by allowing UPS to hand off our packages to USPS who decided to be completely foolish and claim to not figure out the address so my charger got sent back to sender. The charger for the Eufy S1Pro is very specific and can only be ordered through Eufy or Amazon (where it’s on back order for weeks.) To summarize Eufy does not have enough parts in stock for their pumps, and cuts costs on shipping at the expense of their customers. I am extremely disappointed as a breastfeeding mom I rely on my pump and clearly I put my faith on the wrong company as I sit here unable to use my $200+ wearables because I cannot even get a replacement fast enough from this company.
