The MSTR B8 Blast Off is a rechargeable automatic stroker built around two powered motion systems: seven thrusting modes and three rotation speeds. Its clear-view windows, strobing color LEDs, and optional realistic moaning sounds add visual and audio effects, while the included suction-cup mount can support hands-free positioning on a suitable surface. Browse the Strokers & Masturbators collection to compare it with other powered and manual designs.
This is a feature-heavy motorized product, not a silent or pocket-size sleeve. The manufacturer lists approximate external dimensions of 10 inches long by 9 inches wide. Its published metric conversions conflict with those inch measurements, so this page intentionally does not repeat them. Measure the intended storage and use area using the inch dimensions and allow room for the controls, mount, charging cable, and safe handling.

The current listing and manufacturer page do not establish a waterproof or submersible rating, a specific charge time, runtime, battery capacity, noise level, earbud connector type, or replaceable-sleeve program. None of those claims is made here. The package and included instructions remain the controlling source for charging, use, lubricant compatibility, disassembly, and cleaning.
Thrusting and rotation controls
The seven thrusting modes change the in-and-out motion pattern, while the three rotation speeds control a separate rotating action. Start with the lowest or simplest setting before combining features. This gives you time to learn the controls and determine whether the motion, sound, and lights are comfortable. Increase one setting at a time rather than beginning with every feature at maximum.
Stop the product before changing position, moving the suction mount, or detaching any part. Keep loose fabric, jewelry, body hair, and charging cords away from moving joints and openings. If the unit stalls, produces an unusual sound or odor, becomes unexpectedly hot, or feels damaged, switch it off and discontinue use. Do not force the mechanism or try to restrain powered movement by hand.
Fit and lubricant planning
The maker describes the tunnel as soft and stretchy, but no universal fit or internal usable dimensions are verified for this listing. Stretch does not guarantee comfort for every body or prevent excessive pressure. Enter gradually, use only a lubricant permitted by the included instructions, and stop if you experience pain, numbness, pinching, loss of circulation, or skin irritation.
When material compatibility is uncertain, water-based lubricant is often the conservative starting point, but the product instructions control. Avoid assuming that silicone, oil, warming, cooling, numbing, flavored, or desensitizing formulas are compatible. Test only as the manufacturer directs and do not use numbing products to mask discomfort. Compare available formulas in the Lubricants collection.
Using the suction-cup mount
A suction cup works best on a smooth, clean, dry, nonporous surface. It may not hold reliably on textured tile, grout, unfinished wood, fabric, porous stone, uneven walls, or dirty or wet surfaces. Clean both the cup and mounting surface as directed, press the cup firmly into place, and test the hold with gentle hand pressure before use.
Mount the unit where a release will not cause a fall, impact, or injury. Do not rely on the suction cup to support body weight, and do not position it above glass, water, stairs, sharp edges, or anything that could be damaged. Recheck the seal during use because motion can loosen a mount even when the initial grip feels secure.
Sound, lights, and earbuds
The moaning-sound feature and strobing LEDs are optional sensory effects rather than performance or safety indicators. Use the included earbuds at a moderate volume and lower or stop the audio if it causes discomfort. The current sources do not verify the connector type or compatibility with other headphones, so use the supplied components as directed rather than forcing an unverified plug into a port.
Strobing lights can be uncomfortable for people who are sensitive to flashing patterns. Stop the light feature if it causes eye strain, dizziness, headache, nausea, or other symptoms. Do not stare directly into bright LEDs at close range. If flashing light exposure is a known concern, consult an appropriate healthcare professional before using that feature.
Charging and battery safety
Before first use, read the charging instructions and use the included USB cord with a compatible power source. Charge on a stable, dry, ventilated surface away from bedding, upholstered furniture, direct heat, and water. Do not operate the stroker while it is charging unless the manufacturer specifically says that is permitted. Never connect a damp product, wet cable, or contaminated charging port to power.
Inspect the cord, connector, port, housing, and battery area before charging. Stop using or charging the unit if it has been dropped hard, cracked, swollen, leaking, unusually hot, giving off an electrical or chemical odor, or behaving unpredictably. Do not open the housing or replace the internal battery unless the instructions describe a user-serviceable procedure.
Cleaning after use
Power the product off and disconnect it from charging before cleaning. Remove only the parts that the manufacturer identifies as removable. Clean the tunnel and any detachable components using the method stated in the supplied directions, then let every part dry completely before reassembly or storage. Do not immerse, rinse, or run water over the motorized housing unless the maker explicitly provides a water-resistance rating and permits that method.
Pay attention to seams, moving joints, clear windows, the mounting interface, and areas where residue can collect. Avoid soaking the controls, speaker area, charging port, or other electronics. A dedicated soft cloth can help clean the exterior without scratching the clear surfaces. Our guide to cleaning and storing sex toys and the broader Materials & Care guide provide general support, but the product instructions take priority.
Storage and inspection
Store the clean, fully dry unit with the charging cord and earbuds organized so they do not bend sharply, pull on ports, or scratch the clear housing. Keep it in a cool, dry place away from direct sunlight, heaters, pets, children, and anyone who should not have access. Do not store it while connected to power or place heavy objects on the motorized mechanism.
Before each use, inspect the tunnel for tears, permanent tackiness, swelling, cracking, sharp edges, trapped debris, or changes in texture. Check the housing and mount for looseness or damage. Retire the product or obtain manufacturer guidance if the material or mechanism has deteriorated; cleaning does not repair damage.
