Sage vs — Comparison

The SMO650 is the Sage SMO650SIL4GUE1 Compact Wave Soft Close 25l 800W Microwave in silver, priced at £179.00. The SMO870 is the Sage SMO870BSS4GEU1 Combi Wave 3 in 1 Microwave, priced at £350.00. In Sage's microwave line-up, the SMO650 is the simpler compact model for everyday reheating, while the SMO870 sits much higher as a multifunction combi option for buyers who want more cooking flexibility from one countertop appliance. That makes the price gap a decision about cooking scope, not simply finish or styling alone today.

The key difference is function rather than brand character. The SMO650 gives you a 25l cavity, 800W microwave output and Sage's soft-close door, so it is focused on quiet, neat countertop use and straightforward control. The SMO870 is not just a solo microwave: its Combi Wave 3 in 1 format adds combination cooking, so it can handle microwave tasks plus oven-style and more versatile cooking jobs that the SMO650 is not designed to cover.

The SMO650 suits smaller kitchens, couples, offices and households that mainly defrost, reheat meals, warm drinks and cook simple microwave dishes. It keeps the spend below £200 and still has the more premium soft-close feel. The SMO870 is better for keen cooks, family kitchens or anyone replacing several small appliances; the trade-off is a much higher £350.00 price and likely more countertop commitment in return for broader cooking capability and fewer separate gadgets.

Bottom line: choose SMO650 if you want a compact 25l, 800W Sage microwave with soft-close convenience at £179.00 and no unnecessary extras / opt for SMO870 if you want the 3 in 1 Combi Wave format and are happy to pay £350.00 for a more flexible cooking appliance.
