Fast Delivery good Good quality

This diffuser is different from the similar-looking 500ml A1 model I previously ordered from AromaLiving.sg. Build quality seems alright for the cheaper price. There are 7 preset LED colors you can manually select from (red, light green, green, cyan, blue/violet, pink/magenta, and white; each with two levels of brightness), or have the diffuser automatically and seamlessly transition through the colors. If you do the latter, you can stop the transitioning at any moment by clicking the light button on the remote, and the light will be the color at that exact moment. So, if you stop the transition anywhere between red and green, you could have any shade of orange or yellow that you prefer (see photo), which would be quite similar to warm white (~3000K) that the (8-color) A1 model has as a color option. Similarly, you could set any color you like in between the rest of the 7 preset colors. Overall, I find the colors of this model more appealing than those in the A1 model, which are a bit garish. And the warm white option of that model isn't so nice either as it seems to have a hint of green. Other than the colors, the other difference is the intermittent function this model has, which starts/stops the diffuser automatically at 30-sec intervals. And of course, the wireless remote control that comes with this model.But the delivery service is another story. Shipping info showed "starting delivery to recipient" at 09:27am on May 21, but it only arrived unannounced, supposedly late in the night at 11:13pm (almost 14 hrs later) and just left at my doorstep. No call to let me know, no messages received, no knock on the door, nothing. That's terrible delivery service by Qoo10, and you can do better than that

Item is compact compared to previous one we had.
