Review on 🛠️ Acekit Bike Headset Cup and Bottom Bracket Press Installation Tool: Effortlessly Install BB30 and BB90 with Precision by Matt Davis

So you need to mount the headset without damaging the frame. At one end of the price spectrum you have the top-of-the-line Park Tool headset press for around $170, at the other end a rubber mallet for $5 (not recommended). This press actually does a pretty good job for about $30 with the following caveats: 1) You take your time and SLOWLY apply force to make sure the press stays properly centered. 2). Make sure you have a good quality long box wrench (24mm I think) to tighten the bottom bolt while turning the pressure grips. 3) Don't forget to put some lube on the headset cups.
