Thinking about buying a Redmi 5 Plus. I have some questions I'm hoping you can help me answer before purchasing.

Hi I live in Ireland and am considering buying a Redmi 5 Plus to replace my failing iPhone 5c. Before I pull the trigger on the purchase I wanted to ask some questions here in the hopes somebody can help clarify some things for me first. Please keep in mind I'm new to the Xiaomi universe so would appreciate any input you may have.

My first concern is that I'm getting the right phone, Xiaomi don't make it easy for first time buyers with their confusing naming structure (eg. Redmi 5, Redmi 5 Plus, Redmi Note 5 Pro, Redmi Note 5A, Redmi Note 5 Prime).

Here is a link to the exact phone I was going to buy and I think this is the phone that is called "Xiaomi Redmi Note 5 (Redmi 5 Plus)" on this site(I tried to add a direct link but the URL had brackets in it so it wouldn't work). Could somebody verify for me if they're the same product? The specs seem to match up but I just want to make sure

Secondly I am on the 3 mobile network and wanted to make sure the bands in the phone would work for me. I tried to use https://willmyphonework.net/ to check if the Redmi 5 plus would work where I live but it didn't have an option for this phone so I selected the Redmi Note 4 assuming the two would be similar ( I looked their specs up and they seem to have all the same bands, the Redmi 5 Plus has one extra). Is it a safe assumption to think that I will get similar performance to that listed for the Redmi Note 4?

I have been shopping around on different sites and found this website called The Solution Shop that offers the Redmi 5 Plus for €145 including shipping and with tax paid. This seems very low compared to other sites I found such as this €168 Redmi 5 Plus from Hong Kong Goldway on Aliexpress. Would you recommend either of these services vs one another. Both list that they are global versions of the phone but the solution shop version specifies English and the Aliexpress one has an image in the ad with Spanish, Polish and Russian circled as the languages but not English. I also couldn't find any written reviews from an English speaking user to confirm the phone worked on either listing. Both links are to the 4gb 64gb version in the same colour.

I don't mind spending extra money to make sure I get a legit product but if they're both safe I may as well save the €23 and buy a Mi Band 2 or something with it.

I have also seen pictures of a Redmi 5 Note Pro and the specs for that seem better but I can't seem to find reliable links to buy it, is this phone available for people in Europe? would you recommend it over the Redmi 5 Plus?

Thanks in advance for your help, excited to join the Xiaomi family
