I feel when the first boost evaporates there's still tension but no elasticity. When I reboost the elasticity is there but the sponge is mushy and doesn't have so much tension.
Now I don't boost at all.
the h3 plays good even after the initial boosting effect is gone, the tension is there and there's enough power. So for cost saving, just boost your H3 neo properly (blue sponge 2.1mm 40 degree or higher) and play till you bubble, if you aren't good enough to bubble an h3 like me then GREAT, it stays there, save money, time, glue, booster, everything.
The orange sponge tho, the performance does drop signfinantly after initial boosting effect is gone so stick with blue sponge. Spend extra $$$ and get the national neo and let it sit for a year or forever if u can't bubble it.
