### ⭐⭐⭐⭐⭐ Spring booster
*by D***R on 19 November 2025*

Worked fine for slightly sagging springs

### ⭐ You only get ONE
*by K***Y on 15 February 2026*

Absolutely pointless!!!! You only get one 🙄 complete waste of time!!

### ⭐ You only get 1 assistor for one spring, so useless.
*by K***R on 8 June 2025*

Er you get just one spring assistor, Obviously useful for lopsided heavy loads. Great sense of humour but a complete waste of time.
