    Things I liked:Being IN STOCK and not having to wait for an overseas shipping. OEM quality at competitive price of aftermarket springs. Great power being these USA spec springs are whats known as FAC power in the UK. Am getting 875fps with H&N FTT 8.64 gr pellets in a .177 MKIII
    Things I would have changed:Provide a "FITTED" spring guide with the spring .... or make sure Sizing of spring is an appropriate fit on OEM guide as delivered from factory.
    What others should know:Sadly QC or production tolerance had springs coil diameters I.D. & O.D. larger than spring it had replaced. Issues was a VERY loose fit on the spring guide. Gun shot fine but vibration and noise was greatly elevated. Needed to have a "Custom" Delrin snug fitting spring guide made which doing so made rifle actually SMOOTHER than it was new ... very solid thump, NO vibration.
