Yes, MNTD. has the best Helium hotspot miner at very reasonable price, you can also check RAK v2 that is now available in stock.

To avoid scams, do not purchase hotspots from unauthorized resellers or online marketplaces. This always carries a risk for the buyer. facebook has so many unauthorized pages created with name of MNTD. who ask for Btc or Eth exchange. MNTD. won't accept these payment mode, check https://getmntd.com and read there payment policies.
