A closer look.
HOTO's product page describes 12 double-ended bits, giving 24 working ends. The linked official manual identifies model QWLSD004. This is the manual pen, rather than an electric precision screwdriver. Which bits are included? The official QWLSD004 manual lists these 24 tip labels across 12 double-ended bits: T2 / T3 / T4 / T5H / T6H / T8H / T9H / T10H H1.5 / H2.0 / H2.5 PH000 / PH00 / PH0 / PH1 SL1.5 / SL2.0 P2 / P5 / TW1 / U2.6 / Y0.6 / W1.5 / ▲2.3 Compare the complete label with the tool specification in your equipment's instructions. A broad description such as "small Phillips" or "Torx" is not enough to choose a size. PH000 appears in this manual; PH2, H3.0 and T15 do not. Will the bit reach the screw? Matching the tip is only the first check. The manual specifies C4 × L30 mm double-ended bits. That is the bit format, not a verified installed reach into a narrow or deep recess. Check the opening around the screw and the available working space before buying. ETVendor has not measured installed reach or tested this pen on your equipment. When is this pen worth considering? Consider it for occasional manual adjustments when the required tip is listed, access is adequate, and keeping the bits inside one handle is useful. If your required size is absent, or a long narrow shaft is necessary, choose a tool that explicitly covers that requirement. Follow the equipment maker's instructions; a matching bit alone does not establish that a repair is safe or suitable. Check the exact buying option The Amazon link on this page is for ASIN B08X6WNPLL, the Slate Grey option recorded as manufacturer part QWLSD004-Black and retail model P1-Black. Keep that retail option separate from HOTO's Charcoal Black store selection. Check the selected finish, seller, current price, delivery and return terms on Amazon before ordering. No current price or stock guarantee is made here.
