The price is right on. These device not designed to last forever. Since most people don't stand by [remain at] their washing machines for the full cycle duration they chose, the shock absorbers take a beating over the years from unbalanced loads to high speed spin cycles. Replace ALL three at one time. This will save you time, energy [multiple washer disassembly/reassembly] and repair costs as part prices have steadily increased over the years.
Outwardly these appear different than the OEM shocks on my washer. However, they appear to be of good quality and corrected the issue of my washer becoming off-balance and "walking" from its position. I've had them in for about 2 weeks/20 loads of laundry and thus far they are holding up well. I'm very mechanically inclined so install was not too difficult. It might be a too much of a challenge for others depending on mechanical abilities along with the design of the particular washer.
