Bought this OEM Portable Laptop Stand from Lazada for S$14.50 during their 4/4 sales day. The usual price is S$15.90. Shipping within Singapore is an additional S$1.49, but I have a free shipping coupon from Lazada.
There are two variants for this portable laptop stand, aluminum, and plastic. The plastic model is P1 Pro and comes in three colors, Black, Pink, and White. The plastic is cheaper, retailing at S$10.90.
Got the Logitech Notebook Riser N110 from Challenger VivoCity for S$37 for my office use. It is to raise my MacBook Pro so that the screen can be placed beside my future monitor for dual screen purposes. In the mean time, it gives me a good elevated viewing angle.
