General replacement timeline
| Usage frequency | Typical replacement |
| Daily use (1–2 hours/day) | Every 6–12 months |
| Weekly use (few hours/week) | Every 12–24 months |
| Shared by multiple users | Every 3–6 months |
These are estimates. Actual lifespan depends on sweat, cleaning frequency, and intensity of use.
Signs it's time to replace
| Component | When to replace |
| Straps | Fraying edges, Velcro no longer grips, stretched out (won't stay tight) |
| Pads | Flattened (no cushion), torn, odor won't wash out, permanent indentations |
Do not wait for complete failure – worn straps can slip, causing falls.
Check before each use
| Quick check | What to look for |
| ETIE button | Normal rotation or pulling out |
| Strap edges | No loose threads or fraying |
| Pad thickness | Still soft, not hard or flat |
Replace immediately if any of these fail.
Does warranty cover straps and pads?
| Question | Answer |
| Covered under warranty? | ❌ No – wear items |
| Can I buy replacements? | ✅ Yes – from Ascentiz spare parts store |
Straps and pads are consumables – like shoe soles or bike tires.
How to extend lifespan
| Tip | Why |
| Hand wash, air dry | Machine drying damages materials |
| Wipe sweat after each use | Sweat accelerates breakdown |
| Rotate if sharing | Less wear per user |
| Store away from sunlight | UV weakens straps |
