Really seem to care about the stuff they sell and were really helpful on the phone, were happy to answer questions after the sale and seemed really knowledgeable. I would definitely use them again. I would especially recommend them if you are otherwise being tempted by eBay phones from China - buying from them you get decent support and the best models have been sifted out for you.

All arrived when it was expected. Everything in the box as expected. Good product but not easy to understand how to use the phone as the instruction manual was inadequate. However, I was warned of this problem in the Mantistech video about the phone. Contact to sort out problems on the phone has been excellent.

Very impressed - how all companies should be. Delivery was rapid and the phone was well packaged. Everything was as advertised. Unfortunately I had a problem with the earphones after they'd been used for a couple of weeks. Getting a replacement set ordered was simple and all was sorted to my satisfaction. I'd happily buy again from Mantistech. Recommended.

I bought the Sapphire XL 5.7 Inch Android 4.1 Jelly Bean Dual Sim Smart Phone because I needed a dual sim with a larger screen mainly for my business's. It's a joy from the brilliant clear screen to it's speed and applications. I also bought the Protective case which I would advise having. When I phoned Mak from Mantistech he was really helpful before and after I purchased the phone. I've got HTC, Samsung & LG mobiles which will be consigned to the bin as none of these come close to this stunning phone.. Give yourself a real treat and Buy this Phone..

used this company for the first time yesterday, ordered my cable at 2.30 pm on tuesday arrived 9.30 am next day awesome service and rapid delivery would definately use again..

If you value the personal touch you can't do any better than this company. Not only did they remember me after well over a year, but Mak took time and care over the phone to help me in my choice and delivered within two days at a good price. His short videos on the website are clear and helpful. What more could you ask?

Top class service, my item arrived well packed and quickly as promised. Kept informed of delivery.

Very helpful on initial telephone conversation, I needed lots of advice as I didn't know too much about the thing I wanted to buy. I did say it was kind of urgent, it was after the guaranteed next day time but they must have run to the post office as it came the next day. The website had a good video demo and all in all I would buy from this company again. I did mention Mantis tech to my brother , he bought the same item and was as happy as I was with it all.

I have previously bought a phone from MantisTech so when I was after a new one they were the obvious choice. I bought the Sapphire Android 4.1 Dual SIM Phone about 2 months ago as I was after a larger screen as well as the dual SIM functionality. As I couldn't wait to get my new phone I decided to go for the registered delivery option and so got my phone the next day. It was well packaged with the box in bubble wrap giving an extra bit of protection. The phone had a screen protector on it albeit with print all over it. (HINT I got a plastic ruler and gently scraped the print off to leave a perfectly usable in place screen protector which still works perfectly today !) So what about the phone? I am really loving the phone as it is fast and responsive with a good quality build ( it has the feel of a Samsung S4 but with a bigger screen ) and the graphics are really clear and bright. The larger screen makes all the difference to its usability, browsing the internet etc. There isn't really any bloat ware just the basic ROM; I have only uninstalled two apps. You get 'Documents to Go' and 'MoboPlayer' which are an office program and video/music player, both free and obviously really useful. The only issue I had with the phone is the way the ROM was partitioned. It has 4GB space, approx. 1.5GB for OS etc. and 1.98 for your files and documents. This gives only approx. 500MB for Apps which for me was taken up really quickly. Fantastic Customer Service Due to the space issue - which as I understand is a restriction Google has created on phones over Android V4.1 - I got back to customer service to see if they could do anything about it. And they could!! I sent my phone back to Mak who upgraded the ROM to give me more internal space for my Apps. I now have nearly 1GB and what's more he has restored the 'Move to SD' button (that Google took off for V4.1). I can now use both my internal memory and the 32GB memory card to install Apps. This gives me nearly 33GB of space for Apps, Files and Documents which is more than the new HTC ONE!! What else can I say? As I have said the upgraded ROM works a treat the screen is really clear and sharp, the camera takes good quality photos up to 13M and the sound and video is great as well. I have watched several films on it (running from the SD card) with no problems. Overall a really excellent product, in my eyes as good as a Samsung or HTC (but with an extra SIM). I would highly recommend this phone to anyone who is thinking of buying it. And if you are after a bit more space, ask Mak to upgrade the ROM before sending it out as I'm sure he's kept the one he put on mine. Most importantly is the excellent customer service you get both pre and post sales. Mantis Tech have really gone out of their way to make sure I was happy with my phone.... and I definitely am happy! :-)
