N4P axis upgrades by TBSTRON3D Store

I recently asked someone TBSTRON3D Store regarding buying all three upgrade kits (for each axis) and they replied it can be done. These are the 3 kits:

X-Axis: New X-axis upgrade guide rail kit (HIWIN guide)

Y-Axis: Y-axis upgrade guide rail kit (HIWIN guide),

Z-Axis: Z-axis Upgrade Kit Full Version Kit

The total cost is a little over 270 USD. That's very close to the printer's cost. Are these upgrades worth it?
