KitchenAid 5‑Speed Dimond Blender

KitchenAid KSB1575ER Diamond Blender

KitchenAid 5‑Speed Dia­mond comes in 3 pack­ages that are iden­ti­cal but dif­fer by capac­i­ty and selec­tion of pitch­ers – (1) 60 oz. dia­mond-shape pitch­er, a (2) 56 oz. sim­ple round­ed pitch­er and (3) round­ed 56 oz. round­ed pitch­er and 20 oz. milling container.

It is equipped with only 670 watts at peak and 550 watts of effec­tive pow­er motor. The machine-based unit inte­ri­or design looks nice and sol­id, but the motor-to-blade cou­pling sys­tem is not so reli­able and part­ly made of plas­tic as a weak side of this gadget.

KitchenAid 5‑Speed Dimond gad­get con­tain­ers are made of heavy-duty and shat­ter-resis­tant plas­tic and designed to han­dle liq­uids up to 180F. The blade sys­tem is irre­mov­able and per­ma­nent­ly inbuilt into the pitch­er what makes this blender quite easy to use and clean. The blades are made of good qual­i­ty stain­less steel; how­ev­er, the spline on the bot­tom of the pitch­er that con­nects the blades sys­tem to the motor dri­ve is made of plastic.

The KitchenAid 5‑speed con­trol pan­el is equipped with 5 speeds, one Ice Crush pre-set pro­gram, and pulse func­tion. What makes this machine quite ver­sa­tile and allows the user to cre­ate an array of var­i­ous recipes.

Although this KitchenAid 5‑Speed Dia­mond machine comes with quite a low pow­er motor, its over­all con­struc­tion still makes this machine quite pow­er­ful, so it is designed to per­form the fol­low­ing functions:

  • Makes decent qual­i­ty drinks, includ­ing greens smooth­ies but requires extra time for pul­ver­iz­ing hard ingredients;
  • Crush­es ice cubes for snow cones, process ice in drinks but will not make ice creams or frozen yogurts;
  • Makes nut milk, and with a lot of efforts, it is pos­si­ble to pro­duce nut but­ter on this machine, but it also will require adding a con­sid­er­able amount of water for this task;
  • Chops veg­gies for sal­sa, mari­nades, and sal­ad mixes;
  • Puree­ing food but requires a lot of liq­uid for smooth consistency;
  • Grinds cof­fee beans, herbs into decent qual­i­ty pow­der, but able to mill only soft grains like oats.

KitchenAid 5‑Speed comes with only a 1‑year lim­it­ed war­ran­ty. The cus­tomer ser­vice is quite sup­port­ive and eas­i­ly replace the faulty units with­in the war­ran­ty peri­od. How­ev­er, the motor does not han­dle over­loads well and not very durable. The plas­tic parts in the cou­pling sys­tem also do not add strength to this gadget.

How to Choose Between the KitchenAid 5‑Speed Diamond and Oster Pro 1200 Blenders

Although these two machines are both quite ver­sa­tile and well-made, the Oster 1200 Pro out­per­forms the 5‑Speed Dia­mond Blender. The Oster pro­duces slight­ly bet­ter qual­i­ty smooth­ies and needs less blend­ing time to achieve the best result than what requires the KitchenAid. The Oster also bet­ter han­dles ice and able to pro­duce iced drinks, snow cones, ice creams, and frozen desserts, while KitchenAid only process­es ice in drinks and shaves it for snow cones only.

The Oster 1200 Pro han­dles hot ingre­di­ents up to the boil­ing tem­per­a­ture, so it will process soup veg­gies straight from the oven and per­fect­ly suit­able for mak­ing bul­let­proof cof­fee. While the KitchenAid can han­dle only liq­uids heat­ed up to 180 F.

The Oster Pro 1200 also has a much stronger and pow­er­ful motor, so it pro­duces smooth purees, hum­mus, and even quite a decent nut but­ter, while for the KitchenAid, these tasks are so chal­leng­ing that they often over­load the motor and cause the machine halt.

Besides, the Oster 1200 Pro has a much bet­ter built and strong motor and rep­u­ta­tion of durable machine that is reflect­ed 10 years motor warranty.


Although the KitchenAid 5‑Speed Dia­mond looks very sol­id and pow­er­ful machine in fact, Oster Pro 1200 is a bet­ter built and much more durable machine. It is also designed to per­form more tasks than KitchenAid. It is also, on aver­age, 40%- 60% cheap­er than KitchenAid and comes with a bet­ter war­ran­ty than con­firms its dura­bil­i­ty. So the Oster bet­ter option when choos­ing between those two machines for cus­tomers who are look­ing for a durable, reli­able, and ver­sa­tile blender but do not want to break a bank.
