Bloody Savage Impact SG5: problems, parts and running costs

Checked: 2026-10-28

Summary

The Bloody Savage Impact SG5 wireless gaming mouse has a weight discrepancy between the US store listing (84g) and the manufacturer’s own specifications (64g), and the battery is not user-replaceable. Running costs are minimal with no subscription fees, but replacement skates cost about $15 yearly if needed. At $59.99 it’s a good buy for gamers who need 8K wireless and a charging dock.

Common problems and fixes

Non-user-replaceable battery — the 300mAh lithium cell is adhesively mounted and not intended for user replacement. When it ages, no officially supplied replacement kit exists, potentially requiring a new mouse. [3][6]
Charging dock design limitation — the RX-62 dock has a captive cable and requires the nano receiver to be inserted to function as a wireless extension. Losing the nano dongle means losing 2.4GHz capability. [3][4]
Battery runtime at 8K unclear — manufacturer’s 80-hour claim lacks test frequency and 8K vs 1K comparison data. High polling consumes more battery energy. [1][3]
Receiver interference risk — all 2.4GHz mice can suffer from router/USB-3 interference or metal PC cases. The extension dock helps, but users should test direct receiver placement first. [1][6]

Parts and consumables

Spare PTFE feet/skates — one pre-cut set included with new SG5. Third-party FeetGlide SG5-compatible set costs $9.99 + $4.99 international shipping. Genuine Bloody replacement parts not available. [3][6][18]
Anti-slip grip tape set — included pre-cut pieces tailored to SG5. Genuine replacement set SKU and pricing not reported. Generic grip tape may fit after careful trimming. [1][3]
RX-62 magnetic charging dock — included with captive USB cable. Acts as receiver-extension with plugged nano dongle. Replacement dock SKU and pricing not reported. [3][4]
USB-A-to-USB-C cable, 1.8m — included, removable from mouse. 5V USB data-capable replacements may work if connector shell fits narrow port. [3][6]

Yearly running cost

No monthly subscription or disposable batteries required. The main periodic expense is PTFE feet replacement. Third-party skates cost $14.98 yearly if replaced annually, though this is not manufacturer-prescribed. Charging costs are minimal — the 300mAh cell consumes about $0.03 yearly at 100 full charges.
