Pal of mine bought one for £20.
We compared the scope with my Kowa 77mm Flourite Crystal lens job , 30x Wide angle at Sealand Rifle range @100m.
The Kowa has fantastic clarity and resolving power.Expensive.
The Aldi was suprisingly good at lower powers.
For looking at .22 holes in good light at 100m it works well.
As the power is increased the image gets bigger but very soft focus and worst at 60x.
So for £20 for general spotting ok.
The zoom for mine alone is c £250 is but as with telescopic sights you get diminshing return for you money as the quality goes up.
The Kowa is used for watching wildlife where I like to see every detail.
With shooting I guess you just need to identify the bullet's impact.
So thumbs up for the Aldi with tripod and scope bag.
