SkyWatcher UltraWide

First, mine reveals a 72Â° FOV instead of the 66Â° mentionned by SkyWatcher!
Pretty affordable and light weight for a high power wide angle eyepiece. But it's got bad kidney bean effect.
There's a bit of color spreading and astigmatism, both about 10% around the edges (the extra 6Â° of FOV is therefor of no use), and is not as sharp as my other eyepieces. Example : details are more distinct using my Meade SP 12,4mm and the 2x Celestron Ultima Barlow (i.e. 6,2mm).
But for a wide angle and long eye relief eyepiece on a budget, it is rather suprising! Orion's Expanse Wide Field are the twins of these UltraWide, so if you can get both, go for the cheapest ones.

Evaluation was done using a 114mm f7.9 Newton and a 200mm f6.0 Dob
