SW-S7105 Replacement Shaver Head Blades for All SweetLF Waterproof Electric Razors SW-S7105 SWSBK7105 Wet & Dry Shavers with Clean Brush

I decided to document the process completely even though several others already did. I was surprised that the whole unit wouldn’t snap down and upon further review there is no way this was meant to fit this shaver even though the model number says it does. However what does work is the blades the foil and the internal clamp thing that locks the blades in. You can swap the old blades and foil out and either use the existing holder or use the new one. You just can’t use the frame. I haven’t tried the black pieces on the inside to see if they fit but it’s possible.These blades used to cost 15$ but prices have gone up. This was about 18$ and required a little tearing down to swap over. You would think since it doesn’t fit the razor why put the wrong model number? Thankfully the internals are the same.Hopefully this write up will be helpful for the next person who buys these

connector to razor was probably installed wrong. Razor would not close. Rather than return and reorder, I used the blades only.Dave Boschen

Frame did not fit razor, but blades could be inserted in old frame

Difficult to clasp. Not all blades connect at the same time.

I needed the frame and not just the blades, the hinge on my original broke. The frame in the replacement kit will not close on the SW-S7105 as is. I had to use the a dremel to trim the plastic so it would close.
