SHARDOR CG305B 64mm Burr Grinder

In this shardor cg305b 64mm burr grinder review, the verdict is simple: the SHARDOR CG305B is the best espresso grinder upgrade under $250 in our 2026 guide, and it ranks number 7 of 9 overall. The CG305B is a 350 watt electric flat burr grinder with 64mm SUS420 stainless steel burrs, 100 programmable grind settings, and a die-cast aluminum body weighing 11.4 pounds. It earns 4.6 stars from 59 Amazon ratings at $249.99, the highest rating in this roundup. Buy it if you want commercial-grade parts and touchscreen dosing at home. Skip it if you want a long review history, because 59 ratings is a thin track record for a $250 purchase.

In practice, the 64mm flat burrs are the real story here. Large flat burrs like these cut beans more evenly than small conical sets, and SHARDOR rates them food grade in SUS420 stainless steel, which resists heat buildup that can dull aroma. Meanwhile, the 100 grind steps let you move from espresso to pour over to cold brew without swapping equipment. The 350 watt motor and 11.4 pound die-cast aluminum housing keep vibration low, so the grind stays consistent shot after shot. On top of that, the LED touchscreen handles dose and grind changes, and the anti-static system feeds a stainless steel grounds bin that limits clumping and chaff. Even so, the 1.1 pound hopper means you should store leftover beans airtight, since a full hopper holds roughly 17.6 ounces.

Value for money comes down to parts per dollar. At $249.99 the SHARDOR CG305B sits under the $250 upgrade ceiling while offering a 64mm burr set, a metal grinding chamber and a 350 watt motor, hardware that usually costs more. By contrast, the cheaper SHARDOR CG301 saves you $80 and carries a much larger review base, which matters if rating volume builds your confidence. If you prefer a proven name, the Breville Smart Grinder Pro is the safer pick in this guide. However, neither matches the CG305B on burr size, aluminum construction or touchscreen control. The honest trade-off is those 59 Amazon ratings: few buyers have reported back yet. Overall, this grinder suits the home barista who wants espresso-capable flat burrs and a commercial-grade build now.
