The Proscale Number Series scales: 111 (aka Snake Eyes), 222 (aka The Deuce), 333 (aka Three-Weigh), 555 (aka Johnny 5) & 666 (aka Satan Scale). These digital scales are tough, durable, and priced right. They are inexpensive and good quality.
The Proscale 222, 333, 555 and 666 are definitely the best low-low cost scales in the market. Each of the scale's numbers indicate two things – how much the scale can weigh in grams and the name of the scale.
The ProScale Number Series of low cost pocket scales are ideal for Schools Science lesson experiments.
If you looking for affordability & simplicity (or if you just like the names of these scales), then you've found the right ones.
