It is a quality construction for its price, get filters to change every month, every three uses the filter needs cleaning,

also get a chlorine and pH test kit

, a tip from professional pool experts is to buy the classic blue chlorine (not thick) and every one or two uses depending on the measurement add 80ml (80ml because the chlorine has 50% chlorine and in 900 liters which is the hot tub that much is proportional)

to bring the pH to about 7.2 you will also need to buy a classic Aqua forte (hydrochloric) in these liters very little type 4 to 5ml) the chlorine and Aqua forte are the most economical and safe solution for its maintenance.

also get a pool skimmer because its filter is not that strong and you will need to sweep and collect any hair or some insect. If there is stagnation the chlorine may create a slippery layer on the walls and bottom so the sponge helps to clean it.

Personally, I have provided myself with about €70 head pillows and cup holders from the same company.

The only downside (besides its maintenance) is that you can't lie down comfortably as the water pushes you to the surface and you can't relax because there are no positions.

There is a solution to this but I haven't tried it yet. There are bottom pillows that are for this reason and you can use some to sit and have somewhere to push with your feet (unless you are over 2.04 meters tall!) so you can relax
