Nevertheless, there are certainly legitimate negative reviews, so I always recommend that you read them Read reviews carefully and revolves around use, durability & quality. What problems did you have? How did the dealer or manufacturer react to problems?

Further points:

👉 Few reviews does not always mean that your chosen product is necessarily bad. Maybe it just hasn't been on the market long enough and hasn't been valued enough as a result.

⚠To check an offer, you can specifically for Amazon "Keepa" or "CamelCamelCamel" to use. Prices are tracked here, so you can see if an offer is really an offer.

Dealers like to use the tactic of adjusting a product from its normal price to a very expensive price, only to later sell it at that normal price (now much cheaper). With this tactic, the retailer triggers a price drop, which signals an offer for many online shops, websites, deal sites, price portals and positions it accordingly or makes it conspicuous. Use these tactics to your advantage and catch the periods before and after these price adjustments. This will certainly require a little time, planning and patience for your purchase.

2. Saving tip💶❗ Always compare the scope of delivery with the price. A low price for a single product can become more expensive if you have to buy something as an option right away or later. A product set with a lot of scope of delivery can then suddenly be cheaper, although the price seems high at first.

3. savings tip💶❗ Don't buy scopes of delivery/equipment or more functions if you can already weigh up that you don't need them or use them little.
