Review: To infinity and beyond - Great starter kit for kids. Easy to assemble, adjust and just have fun with.
Review: Worked better during day for us than night - Now I’m not a telescope pro or anything nor know much about them but I at least thought when I got this for our son he may be able to see the moon at night we tried but it’s always been fuzzy and crappy looking maybe it’s us ‘user error’ I donno because I bought this solely based off the reviews I read thinking it’d work good but it sat in the closet all year I wish I returned it . It’s 2023 and hard to believe there’s nothing out there yet we can see the moon with cheap - I’m not asking for a nasa telescope here but that’s what I thought I could at least use this for - however during the daytime I did use it to look over a field and the resolution wasn’t too bad to see birds from far away after you get the focus to set in just right but if you move it the least lil bit you have to readjust everytime - unfortunately it didn’t work out for us and my 9 yr old had an awful time trying to use it as well. All in all maybe it does work well I’m just reviewing solely based on our experience so if you wanna buy to try it go ahead maybe you will have better luck than us !
