Thanks Flexispot. First of all, the delivery was fast, I ordered at 6th Feb and it arrived before Chinese New Year-10th Feb.
I bought this EC1 model as my preferred table top size: 150×75 which also within my budget.
The instruction is very straight forward, in fact you can also customize the way according to your power setup.
The motor sound when adjusting the table height is minimal and bearable.
This is excellent choice while still within budget.
If you have higher budget, E3's faster adjustment (3 programmable memory setup) will definitely benefit the user.
Everything work flawlessly from myside. My recommendation for table top color will be maple for aesthetically looking.
