What it is
Bonny's LeiSu 800 sits in the speed-attack lane. The source review describes a 4U/G5 racket with a narrow NF800-style low-drag frame, 76-hole pattern, foam-filled frame construction, 40T carbon plus nickel-titanium shaft material, a 6.5mm solid shaft, and a 30 lb warranty tension. In plain terms: this is built to swing quickly, stay stable at contact, and reward players who can actually load a stiffer shaft.
First feel
The reviewer removed the base grip and played with an overgrip, which increases the visible head-weight sensation. Even then, the swing weight is described as manageable. The sweet spot is not huge, but the frame gathers power cleanly when contact is centered. The hit is direct rather than sticky, with little unwanted vibration, which is exactly what you want from a fast attack frame: no dramatic dwell, no vague feedback, no soft delay.
Power and control
The standout is power transmission. With JS63 at 28 lb, the source review describes both full smashes and stick smashes as heavy, fast, and easy to repeat for players with good force concentration. The racket's anti-torsion behavior also matters: it does not twist around the shuttle on off-center pressure as much as cheaper speed frames often do. That stability turns into better placement on drives, punch clears, and smash follow-ups.
Speed play
Flat exchanges are where the LeiSu 800's frame shape pays off. The ultra-thin box profile keeps response quick, and the direct stringbed feel makes blocks and counters leave the racket fast. This is not a soft defensive helper for beginners. It is a racket that expects the player to meet the shuttle early and use the frame speed to steal time.
Limits
The same traits that make LeiSu 800 exciting create the buying risk. The sweet spot is moderate, the shaft leans stiff, and the racket wants clean mechanics. Beginners or players with slow preparation may find it harsh or unforgiving. Players who already like Nanoflare 800-style frames but want a lower-cost, more solid-feeling alternative will understand it much faster.
Who should buy it
Buy the LeiSu 800 if you are an intermediate-to-advanced player who wants one racket for singles control, doubles rear-court pressure, and fast mid-court countering. Skip it if you need sugar-water forgiveness, a large sweet spot, or a very low entry threshold. This is one of the better arguments for looking beyond the major three brands, but it is still a performance racket, not a shortcut.
