S3 vs S5: Which SmartShave Razor Should You Buy?

Choose between SmartShave’s 3-blade and 5-blade systems with a clear look at comfort, routine and refill choice.

If you are deciding between SmartShave S3 and S5, the key difference is the cartridge system: S3 is the 3-blade option and S5 is the 5-blade option. Neither is automatically right for everyone. Your skin, hair, shaving frequency and personal preference should guide the decision.

The main difference: three blades or five

When might S3 be the right choice?

The S3 system may appeal if you prefer a 3-blade cartridge and want to keep your setup straightforward. SmartShave’s SB3 and CB3 models are the 3-blade choices in the range. Consider how the handle feels in your hand, how easily you can reach the areas you shave and whether the cartridge suits your technique.

When might S5 be the right choice?

The S5 system may appeal if you prefer a 5-blade cartridge. SmartShave’s GG5 and BB5 models sit in this range. If you already know you like a five-blade format, S5 is the natural system to compare. Remember that blade count alone does not guarantee a closer or more comfortable shave.

Compare the starter kit and ongoing refills

SmartShave’s website currently lists starter kits at £9.99, with a handle and an initial cartridge. The SELECT option is listed at £24.99 per month with four replacement cartridges. Check the current product page to confirm the exact model, cartridge count and plan terms before purchasing.

Important compatibility point: S3 and S5 use different replacement cartridge types. Choose the correct system for your handle when ordering refills; do not assume the cartridges are interchangeable.

Which one should you choose?

Choose S3 if…

  • You prefer a 3-blade cartridge.
  • You want to try the SB3 or CB3 models.
  • You have compared the handle and cartridge details and prefer this format.

Choose S5 if…

  • You prefer a 5-blade cartridge.
  • You want to compare the GG5 or BB5 models.
  • You already use and like a five-blade shaving system.

Four things to check before ordering

  • **Model:** confirm whether you are buying SB3, CB3, GG5 or BB5.
  • **Cartridge type:** make sure the replacement blades match the handle.
  • **Total cost:** compare the starter kit price and the ongoing SELECT cost over the period you expect to use it.
  • **Delivery schedule:** check how many cartridges arrive and when the next payment is due.

Our practical recommendation

If you are undecided, choose based on the blade format you already know you prefer, then check the handle design and the current product details. If you have not used either format, consider what feels comfortable rather than assuming five blades must be better than three. The best choice is the one that suits your own routine and that you can refill confidently.
