How not to crack for any of the security gadgets: Police Day Bomb, Alcohol Tester Breathalyzer Digital Breath, LCD Display Analyzer, Portable Alcohol Detector, spy cams, Security Player Gadgets, and nanny cams.

With each visit of the sites, you will find good plans and incredible promotions on the biggest brands of this universe but at the time of the purchase, there are essential to take into account.

A lack of product information

A web catalog does not work as the shopkeeper thinks in terms of product knowledge, unlike a shop, the user needs to be very knowledgeable. The products presented on your website should have a detailed description and useful to customers, comprehensive and comprehensive information and product.

If you are buying a second-hand gadget, the seller should indicate how often or in what period the item was used, if it was repaired or if it was damaged, even slightly.

If it seems to be missing information, contact the seller. Most sites allow an email to be sent to the seller and the seller usually responds fairly quickly (after all, he wants to sell his gadget, right?). If he is slow to answer or responds vaguely and goes around the bush, it is suspicious.

Are there accessories or not?

Compare apples with apples. For two similar offers - including wear and condition of the item in question, see if any of them include accessories (charger, batteries, case or carrying bag, etc.), packaging or the original bill - people who keep the packaging often pay more attention to their belongings than others, if I rely on my personal experience.

Now that you have checked the external envelope of the gadget, you will have to check if all the internal components are working normally. Come with your different cables and make sure everything works without difficulty.

Current price for this product or similar product

If the product is still on the market, visit several stores or sites to learn about the price of a new or used, or a similar model or product, then compare.

Do not buy in any shop

First important step: the choice of the shop. When you have the choice, prefer an online store that you already know by fame or because you have already used it. Make sure that the general terms and conditions of sale are accessible; the physical address of the company must be clearly indicated with a means of contact (phone, email).

If you have no choice and you have doubts about the reliability of a seller, do not hesitate to contact them by phone or email under the pretext of checking the availability of a product. Do some research on the internet with the name of the shop or ask the community's opinion in our pre-purchase advice forums to find an alternative or collect opinions.

Behind each ad, there is someone who is looking to get a good price for his property. And because not all people are always animated with the best intentions in the world, it's important to make sure that whoever offers the latest fashionable terminal at an unbeatable price is not a rogue trying to get away from you. a gadget that looks like two drops of water to the original.

There are several approaches to avoiding a scam: you can play your contacts (maybe a friend of a friend is selling his device?) And watch the ratings left by other users if the site on which you could close your transaction has such a confidence indicator. This kind of information, which is found on eBay or Amazon, is very useful for the user who wants to assess at a glance the reliability of an advertiser.

Meet the seller and test the gadget

Also make it clear from the outset: tell him that you would like to meet him in person in order to take control of the device and check if it is in good condition.

Also indicate your desire to conduct some tests on it, without necessarily specifying which, to make sure everything is in order. The mere fact of showing you as picky in the acquisition of the gadget will allow you to sort the wheat of the chaff.

Watch out for scams!

Make sure that the site on which you buy your gadget has a satisfaction or refund policy, in case the seller does not send the item or send a different one.

Also, make sure the item is not stolen (having the original bill often eliminates this possibility).

Detect hidden bugs and defects

Now that you have checked the external envelope of the gadget, you will have to check if all the internal components are working normally. Come with your different cables and make sure everything works without difficulty.

Play with your levers sparingly

Another element that you can highlight during the negotiation is the absence of a guarantee when the user who is now trying to sell his property has benefited from it.

 By playing on this aspect, you can very well point out that you will eventually have to make additional purchases to protect the gadget (a case ...) and a discount roughly equivalent to their purchase would be a gesture that you would greatly appreciate.

Of course, if all this is provided with the device, no need to lose your saliva!

In this regard, do not hesitate to ask for the invoice if the user still has it in his possession to know the date of purchase, if the warranty has expired and, if applicable, the conditions for the benefit.

Finally, do not expect incredible discounts. A good deal is above all a deal in which each party leaves with the feeling of not having been wronged. Of course, as a buyer, you will be especially careful to make the biggest possible savings while getting the gadget of your dreams.
